Tangless Inserts:

FOD-Free Design: No tangs to break off, retrieve...or lose.

Approved for use on military programs by NASM8846 and NAS1130.

Cost Reduction: Significantly decreased installation and inspection time.

Bi-directional design eliminates insert orientation requirement.

Quick, non-destructive removal prevents damage to castings.

Tangless Inserts meet the requirements of NAS1130 and NASM8846, and were added to NASM8846, the

procurement standard for helical coil inserts to give you the option to use the Tangless design on military

programs. Paragraph 6.3.1 of NASM8846 states “The decision to select tanged inserts or tangless

inserts shall be made by the design activity.”

Tangless Inserts are designed to replace tanged helical coil inserts as specified

in NASM122076 and NASM124651 series (standard thread) and NASM21209

(locking thread); they install in standard STI tapped holes per NASM33537.

Installed inserts provide a finished thread meeting the requirements

of FED-STD-H28/2 and accept standard bolts or screws (MIL-S-7742)

or UNJ (MIL-S-8879).

Tanged Inserts:

Lower pricing than competitive inserts.

Complete range of locking and free-running sizes, bulk or strip-feed, including metric.

Full line of taps, gages, hand tools, air tools, and electric tools

available...interchangeable with and will install all major brands

of inserts.

Meet or exceed all applicable military, aerospace, and

commercial standards. Full traceability.

Design and Application Assistance: over 25 years of

manufacturing and engineering experience.

In either their tanged or Tangless configurations,

CoilThread Inserts are economical, helically-coiled fasten-

ing devices that provide permanent, wear-resistant screw

threads that exceed the strength of most parent materials.

They protect tapped threads against failures due to strip-

ping, seizing, corrosion and wear. They save time and

money because of their low initial cost and permit flexibili-

ty of installation when using Kato tools detailed in the tool-

ing section of the catalog.

CoilThread Inserts are made of cold-rolled Type 304 stain-

less steel wire (AS7245), work-hardened to a tensile

strength above 200,000 psi and a hardness of Rc43-50.

The finished surface (8-16 microinches) is exceedingly

smooth, virtually eliminating friction-induced thread ero-

sion.

When assembled in STI tapped holes, CoilThread Inserts

form Unified Coarse or Unified Fine threads that conform to

National Bureau of Standards Handbook H-28, Screw-

Thread Standards for Federal Services, Classes 2B and 3B.

Assembled CoilThread Inserts will also accommodate UNJ,

MIL-S-8879, male threaded fasteners.

CoilThread Inserts

CoilThread Inserts are precision-formed continuous heli-

cal coils. With minimal wall thickness, they are the most

compact and lightweight inserts available.

Cross section view shows just how little extra hole diam-

eter is needed to provide the outstanding thread strength

that CoilThread inserts offer.

HIGH TENSION ANCHOR

The high tensile coils of a CoilThread Insert undergo a diam-

eter reduction during installation. The outward spring-like

force of the coils“locks” the insert into place.

Each coil can flex independently to contact the greatest

amount of parent material thread surface. Both static and

dynamic load bearing capabilities are improved.

PARENT

MATERIAL

Performance & Features

CoilThread inserts improve the reliability of fastening systems.

The resilient characteristics of each coil in the

CoilThread insert allows it to adjust independently to

secure the maximum surface contact with individual

threads in the parent material. As a result, loads are

distributed more evenly. Stress and fatigue concen-

trations are reduced to maximize thread strength and

increase the reliability and life of the fastening

system.

The stainless steel used resists corrosion under nor-

mal environmental conditions. Galvanic action with-

in the thread assembly is reduced, further adding to

the life of the fastening assembly. These inserts are

used with temperatures from –320° F. to +800° F.

TANG

Used to drive insert into

tapped hole. Can be left

attached or removed per

requirements of the

application.

PREFORMED NOTCH

Simplifies removal of tang

if required.

DIAMOND SHAPED

CROSS SECTION

Keeps insert weight to a

minimum and allows the

smallest possible hole

diameter.

HARD WEAR-RESISTANT THREADS

Work-hardened, stainless steel forms a smooth, hard surface

that reduces thread wear and resists corrosion. Result: A highly

reliable, long-life insert.

COILOCK THREAD

LOCKING ELEMENT

CoiLock Self-Locking

Inserts incorporate one

or more coils with

straight run segments

that apply pressure to

and lock the threads of

the male fastener.

Additional information on

these Self-Locking

Inserts can be found on

Pages 6 and 7.

CoilThread Inserts provide design and

manufacturing flexibility.

Design opportunities are provided by the structure of

these inserts. Because of the continuous helically-coiled

design, they need no thick wall structure to support the

internal and external threads: the diamond-shaped coil is

the thread!

The inserts can be installed in reduced-size bosses or

flanges and within constricted areas, thus saving space

and weight while providing high strength. A boss radius

equal to the nominal bolt diameter is usually sufficient.

KATO Tools provide a choice of installation methods best

suited to specific production techniques. Convenient

hand tools can be supplied for small runs, repairs and

prototyping: or high-speed electric or air-powered tools

may be selected for rapid, low-cost installation.

CoilThread Inserts are available in Bulk and on Strip Feed

Reels...providing flexibility for any production set-up.

INDEPENDENT THREAD COILS

Corrosion Protection:

Corrosion is the deterioration of a metal because of a reaction

with its environment. The products of corrosion vary widely

from the flaky red rust of iron to the relatively benign oxide over

aluminum. In general, corrosion should be avoided or mini-

mized where possible.

There are many types of corrosion, but a particular type called

galvanic corrosion is most important for inserts and fasteners.

Galvanic corrosion occurs when dissimilar metals are in con-

tact in the presence of an electrolytic solution. All metals exhib-

it different degrees of “activity” or “nobility” and can be

arranged in a galvanic series of increasing activity. Gold and

platinum are most noble while zinc and magnesium are most

active. The most common electrolytic solution encountered is

ordinary water. Seawater or salt spray is more damaging

because of high concentrations of dissolved salts.

The best way to preclude galvanic corrosion is to use similar

potential metals and eliminate the electrolyte conductor. The

active stainless steel CoilThread Inserts are not passivated. This

minimizes the possibility of galvanic corrosion occurring when

they are installed in aluminum or magnesium parent materials.

Some additional precautions for reducing galvanic corrosion

are:

1. Isolate the fasteners from the electrolyte. This can be done

through gasketing or sealing.

2. Specify cadmium plated inserts. The cadmium plate pro-

vides a sacrificial barrier against corrosion. In addition, the cad-

mium plate has lubricating properties that minimize galling

when stainless steel screws are used.

3. Apply corrosion inhibiting pastes or compounds to the

screw. These include zinc chromate primer (MIL-P-8585) and

strontium chromate primer (MIL-P-23377). Note: Pastes

applied to the CoilThread Insert can become trapped between

the wire and the hole and cause loss of proper tolerance. It is

therefore recommended to apply the paste only to the screw,

not the insert. If zinc chromate primer is applied to the tapped

hole it should be thinned and applied sparingly. The insert

should be installed while the primer is still wet.

4. Specify a dry film lubricant such as molybdenum disulphide

on the inserts. This provides a secondary barrier against cor-

rosion.

5. Where practical or where it will not interfere with the com-

pleted assembly, the external joint should be coated with a suit-

able paint.

Selection of Correct Insert Length

CoilThread Inserts are available in nominal thread sizes

from UNC #2 through 1-1/2,” and from UNF #3 through

1-1/2.” Metric sizes include M2.2 through M12. Five

insert lengths are available for each thread size.

It is important to select the correct insert length in order

to balance the bolt tensile strength against the shear

strength of the parent material.

These five insert lengths (recommended thread engage-

ment of the CoilThread Insert), 1, 1-1/2, 2, 2-1/2 and 3

are shown in the shaded area of the table below. These

are calculated numbers since the inserts cannot be

measured in the free state. The numbers are multiples of

the nominal thread size, or diameter, of the insert. The

actual insert lengths in the installed position are listed in

the insert selection tables. There they represent the

actual installed length plus 1/2 pitch.

Using the table below, an insert length can be selected

which will produce a thread system strong enough to

fracture a bolt before it will strip or damage either the

parent material or the insert.

Bolt Projection

Standard, readily available bolts and screws that require

no special hardware are used with CoilThread Inserts.

The bolt must engage the entire insert length to achieve

maximum assembly strength. To insure against partial

engagement, it is recommended that the tang always be

removed. This will also guarantee that the locking coil(s)

will be engaged by the full threads of the bolt. If design

parameters prevent this, contact the KATO Engineering

Department for assistance.

NOTES:

1. Bolt tensile strengths are specified minimums. When

choosing an insert length, consideration should be

given the maximum tensile strength allowed by the

bolt drawing or procurement

specification.

2. Service temperatures can cause significant variations

in strength values, therefore compensation should

be allowed.

3. The importance of shear values should be kept in

mind because the parent material is subject to shear

ing stress near the major diameter of the tapped

threads.

4. When the strength values fall between two values in

the table above, use next lower material shear value,

or the next higher bolt tensile strength value.

5. To achieve maximum strength, bolt length and thread

length as well as full tapped thread depth must be

sufficient to assure full thread engagement over the

entire length of the insert.

6. Specific charts detailing load values by thread size

are available: contact the KATO Engineering

Department.

CoiLock Inserts exert a prevailing torque on male thread-

ed fasteners to prevent loosening due to vibration or

impact. They eliminate the need for other, less desirable

and costly locking mechanisms. They are excellent in

adjusting screw applications by preventing the male fas-

tener from creeping.

How CoiLock Inserts work

One or more of the coils in the insert have a series of

straight segments. Upon entry of the bolt these straight

segments are flexed outwardly, creating pressure on the

bolt. This pressure is applied between the flanks of the

bolt thread so that contact area is maximized and unit

pressure is minimized. It is often possible to realize cycle

life far in excess of specification requirements.

CoiLock Self-Locking Inserts – Tangless & Tanged

Location of Locking Coils

For 1, 1

, and 2 diameter lengths: The center of the lock-

ing coil (or coils) equals

the number of free coils. For

and 3 diameter lengths: The locking coil is located

the same distance from the tang as 2 diameter length

inserts. For Tangless inserts, the center of the locking

coil equals

the number of free coils.

Locking Torques

Unified size CoiLock Inserts conform to NASM21209

(Tanged) and NAS1130 (Tangless) and produce locking

torques in accordance with NASM8846 when used with

heat treated cadmium-plated bolts. When using heat

treated unplated or stainless steel bolts, an anti-seize

compound, e.g., molybdenum disulfide, must be used in

order to minimize galling and assure maximum cycle

life. Wear life of screw or bolt using CoiLock Inserts can

also be improved by specifying dry film lubrication or

cadmium plating.

KATO engineers are available for consultation on appli-

cations using brass or aluminum screws, low torque

adjusting screws and severe high torque requirements.

CoiLock inserts in Unified sizes are dyed red for easy

identification purposes only. It is alcohol soluble and can

be removed if desired. (Metric locking inserts are not

dyed red.)

Torque Units -Conversion Factors

Drilling the Hole:

Drilled hole dimensions are tabulated on pages

10–13. The minor diameters tabulated conform to

NASM33537 (inch sizes), and MA1567 (metric sizes), and

must be met after tapping.

The drill sizes shown are recom-

mendations only, based on expected

material behavior and for increased

tap life in harder materials. Actual

individual conditions may require

varied drill sizes in order to produce

the correct minor diameter after

tapping.

The Minimum Drilled Hole Depth is designed to allow for:

1. The use of standard countersink as tabulated.

2. The use of standard Screw-Thread Insert (STI) plug or

bottoming tap for the maximum tool life.

3. The use of the standard installation set-down of 3/4 to 11/2

pitch below the work surface.

The “F” dimension minimum is based on installed insert

length, plus set-down, plus tap chamfer length, plus chip

clearance.

For plug taps with a nominal diameter of 5/16” or smaller the

“F” dimension minimum allows for a male center on the tap

equal in length to nominal tap diameter divided by 2.

Minimum Material Thickness for Through Holes:

The nominal insert length is the minimum through hole

length (material thickness) without counter-sinking and with

the insert located 1/4 to 1/2 pitch below the top surface. With

normal countersink and set-down, the minimum through

hole material thickness equals “H” dimension, the minimum

full thread depth...or minimum tapping depth shown tabulat-

ed on pages 10–13.

Edge Distance Minimum:

For most materials, a minimum edge distance equal to the

nominal bolt diameter may be used when measured from the

centerline of the hole.

Countersinking:

Countersinking dimensions are also tab-

ulated on Pages 11 and13. These con-

form to NASM33537 and MA1567.

Before tapping, it is good practice to

countersink 120° ± 5° to “M” diameter in

order to prevent a feather edge at the

start of the hole. The 60° per side coun-

tersink angle is used because it is the

same as the angles of the tapped thread, insert cross section

and inserting tool prewinder tip. This combination provides

for smooth and rapid production installation.

The “F” and “H” values are calculated with a

countersink depth of 1/2 pitch.

Tapping:

The pitch diameter limits shown tabulated

on pages 11 and 13 conform to

NASM33537 and MA1567 and must be

met in order to assure proper thread fit

after installation of the CoilThread Insert.

CoilThread Inserts are normally installed

3/4 to 1-1/2 pitch below the surface of the

parent material in counter-sunk holes.

Modification of this set-down depth may

be made to suit certain limitations. Without

a countersink the inserts are typically

installed 1/4 to 1/2 pitch below the surface.

KATO STI Taps are for free machining materials. Four

styles are included see pages 14, 15, and 17):

1. Plug Style: Provides easy starting for through holes

and blind holes.

2. Bottoming Style: Ideal for blind holes that are drilled

to a minimum depth. Also for blind holes that require

threads to be close to the bottom of the hole.

3. Spiral Pointed Style (Plug): Free-cutting suited for

use in long through holes and in blind holes with

ample chip clearance.

4. Spiral Flute Style (Bottoming): Pulls chips out of

deep or blind holes in soft materials.

Roughing Taps are also available for use where tapping

operations are difficult. These reduce the load on the fin-

ishing tap. Contact KATO for availability.

As in drilling the tap “H” dimension limits are recommen-

dations only and may be varied where necessary to pro-

duce the required class of fit. CoilThread Inserts are iden-

tical for the various classes of fit. The class of fit is con-

trolled by the tapped hole tolerance.

The class of fit specifies the pitch diameter tolerance,

with 3B (inch) and 4H (metric) being the tighter ranges

and usually specified for military/aerospace applica-

tions. The tighter classes of fit are recommended when

using locking-type inserts for more consistent locking

torque. Class 2B (inch) and 5H (metric) tapped holes

provide a broader tolerance range, and are frequently

specified for commercial/industrial and thread repair

applications.

The minimum tap depth “H” dimension is calculated for use

of a standard countersink and standard insert set-down

depth. Modification of set-down or elimination of counter-

sink will permit a corresponding reduction in thread depth.

All tapped hole dimensions must be met after application of

any desired surface finish such as anodize.

Gaging:

KATO STI Plug Gages used to check the tapped holes are

described on pages 16 and 18.

Working gages are recommended for production use

since their greater tolerance allows for more wear.

Reference gages have pitch diameters at or very close to

basic size and are to be used as master gages.

Installation of the Tanged CoilThread Inserts:

CoilThread Inserts may be installed with tools conforming

to A-A-59158.

KATO tools for inserting, tang breakoff and insert extrac-

tion are also included on Pages 37-42 and 48-50.

The accuracy of the finished thread with the CoilThread

Insert installed depends upon the accuracy of the tapped

hole. If the tapped hole gages correctly, the installed

CoilThread Insert will be within the thread tolerance. No

further gaging is necessary. If gaging is attempted after

the CoilThread is installed, the GO thread plug gage may

not enter freely...however, the insert will seat itself when

the bolt or screw is installed and tightened. (Reference

NASM33537 and MA1567)

Tang Removal:

It is recommended that the tang always be removed to

insure that the full threads of the bolt fully engage the

locking coils when using CoiLock Inserts. To achieve max-

imum assembly strength the bolt must engage the entire

insert length.

Note: If necessary, CoilThread inserts can be removed

from their tapped holes even after tangs have been

removed. Removal tools are listed on pages 42 and 50.

Power Tools:

For rapid installation, KATO Power Tools are available.

These are detailed on Pages 38-41 and 49.

Notes:

Standard size drills are suggested even though some sizes may vary slightly from the specified minor diameter limits.

Metric size drills may be substituted, provided they fall within the minor diameter limits.

For plug taps with a nominal diameter of M8 or smaller, (F) minimum allows for a male center on the tap equal in length to

nominal tap diameter divided by 2.

Dimensions shown are in millimeters (mm).

(For free machining materials)

For general hand and machine operations.

To order, add the pr

efix CTC- to all Unified Coarse part numbers tabulated, and add CTF- to all Unified Fine part

numbers. Example: CTC-02SRP-H1.

Easy

starting for

through-holes and

blind holes.

Ideal for

blind holes

that are drilled to

a minimum depth.

Free-

cutting for

use in long

through-holes

and in blind holes

with chip clearance.

Pulls chips

out of deep or

blind holes in soft

materials.

Provide chip disposal in tapping operations.

The“H” limit number (last digit in Part Numbers above) indicates the number of .0005 inch increments the tap’s maximum pitch diameter is above the

basic (minimum).

The Class of Fit specifies the pitch diameter tolerance of the tapped hole, with 3B being the tighter range usually specified in military/aero-

space applications, and when consistent locking torque is desired when using locking inserts. Class 2B taps provide a broader tolerance range

or looser fit, and are normally specified in commercial/industrial applications. The class of fit of the installed insert is controlled by the class

of fit of the tap.

STI Thread Plug Gages – Unified Sizes

KATO STI Thread Plug Gages are used to

check the accuracy of the tapped hole. If

the tapped hole is correct, the finished

thread will also be accurate when the

insert is installed. It is not necessary to

gage the installed insert.

You will note that both “Working Gages”

and “Reference Gages” are shown tabu-

lated. Working Gages are recommended

for use with production since their

greater tolerance allows for more wear.

Reference Gages have pitch diameters at

or very close to basic sizes and are to be

used as master gages.

NOTES:

1. The Working Gage “GO”

member has a .0002 wear

allowance on the pitch diameter.

2. Gaging of the tapped thread is

specified because a standard

gage may not freely enter an

installed insert. The insert will

seat itself once a bolt or screw

is installed and tightened.

(REF. NASM33537.)

3. KATO STI Gages comply with

A-A-59158.

4. The “GO” member checks basic

pitch diameters, major diameter

minimum and lead. The “HI”

member checks maximum pitch

diameter. Minor diameter is

checked separately with a grad-

uated pin set, for example.

chip clearance.

The Class of Fit (4H or 5H) specifies the pitch diameter tolerance of the tapped hole, with 4H being the tighter range usually specified in

military/aerospace applications, and when consistent locking torque is desired when using locking inserts. Class 5H taps provide a broader toler-

ance range or looser fit, and are normally specified in commercial/industrial applications. The class of fit of the installed insert is controlled by the

class of fit of the tap.

Kato STI Thread Plug Gages are used to check the accuracy of the tapped hole. If the tapped

hole is correct, the finished thread will also be accurate when the insert is installed. It is not

necessary to gage the installed insert.

Notes:

1. Gaging of the tapped thread is specified because a standard gage may not freely enter an

installed insert. The insert will seat itself once a bolt or screw is installed and tightened.

2. The "GO" member checks basic pitch diameters, major diameter minimum, and thread lead.

The "HI" member checks maximum pitch diameter. The minor diameter is checked separately

with a graduated pin set, for example.

Optional Finishes

Dry Film Lubricant Coating:

Tangless Inserts: Add "W" suffix to Tangless Insert Part No. (see page 26.)

Tanged Inserts, Free-Running use MA3280- part number prefix.

Tanged Inserts, Locking use MA3330- part number prefix.

Cadmium Plating:

Tangless Inserts: Add "Y" suffix to Tangless Insert Part No. (see page 26.)

1. These tools are designed exclusively for use with the new KFS Electric Driver with the

Quick Disconnect Hex Chuck.

2. Metric Inserts have finer threads then their corresponding inch sizes, making them

more difficult to install. Because of this, KFS recommends that Prewinder Type Tools be

used for hand installation, and Air Driven Tools be used with Strip-Feed Inserts for

power installation.

3. Metric Tangless Inserts require a separate Tool be used for Free-Running Inserts, and

Locking Inserts (see table). This applies only to the Hex Shank Insertion Tools.

4. Please contact KFS for technical assistance in choosing the optimum style tool for

installing Metric Tangless Inserts, and for availability of Hex Shank Tool sizes.

Sample Part Number (see full description above)

Nominal length is a calculated number and cannot be measured in the free state. It is the actual installed length plus 1/2 pitch.

Number of free coils is the total number of convolutions and has a tolerance of ± 1/4 coil. Convolutions are counted by starting 90º from the tang for all fine sizes and for

Coarse sizes 5/8” and smaller. For Coarse sizes 3/4” and up convolutions are counted by starting 180º from the tang.

Packaging:

Supplied in bulk or on strip-feed in sizes through 5/16” Dia. for power installation.

SF = Strip-feed. Leave blank for bulk.

Finish:

W = Dry film lubricant

Y = Cadmium plated

Leave blank if none is required

Nominal Length:

See tabulation below. Shown as 4-digit number without the decimal point.

KATO Air Driven Installation Tool

The Air Driven Installation Tool consists of the Air Motor, Adapter, and Front End Assembly. It can be used to

install Tanged or Tangless Inserts, inch or metric sizes. The Front End Assembly is the only component that

changes depending on the thread size, whether the inserts being installed are Tanged or Tangless, and if they

are inch or metric.

A different Front End Assembly is required for each insert thread size.

Features:

• Adjustable for different insert lengths and installation depths.

• Semi-automatic installation.

• Strip feed speeds installation.

• Lightweight; can be used free-hand or with tool holder.

• Compatible with competitors’ inserts and tool components.

The Air Tool can be mounted on the Kato Radial

Arm Tool Holder, Part Number CT21042.

Select KATO Air-Driven Installation Tools to provide

heavy duty service for high volume production runs.

Use vertically mounted in the KATO Power Tool

Holder or freehand at any angle; a complete tool

weighs little more than a pound. Operation is simple

and semi-automatic: light thumb-pressure on a single

lever prewinds and drives inserts into threaded hole:

release of lever automatically retracts mandrel, reset-

ting tool for the next insert.

Electrically Driven Installation Tools –

for Tanged Unified Size Inserts

This UL-approved electric tool is an alternate to hand

installation where increased production is required.

Ideal for clean room applications, it is lightweight, easy

to use and runs cleanly and quietly. Operates without

operator force and without lubrication. It is also excel-

lent for reaching tapped holes in constricted areas.

Features:

• Tool automatically reverses itself when preset torque

is reached.

• With interchangeable fully-threaded mandrels, tool

installs inserts of varying sizes and lengths.

• Unique design minimizes mandrel wear.

• Knurled control sleeve is rotated quickly and easily to

set required torque (from 0.5 to 4.5 inch-lbs.)

• Installation depth is easy to set. Locks into place

with a stop nut.

• A separate override “forward” and “reverse” switch,

in convenient location at top of tool, assures con-

trolled operation.

Transformer plugs into standard 110VAC outlet.

Torque Adjustment:

1. Reduce torque (by turning knurled sleeve outward)

until insert will not install.

2. Increase torque gradually (by turning knurled sleeve inward)

until insert installs properly. (Do not use higher torque than

necessary to install insert.)

Insert Installation:

Figure 1

Place insert on mandrel with tang firmly engaged on tip.

Figure 3

Installation Instructions

Hold tool in line with tapped hole and install insert, using low

speed setting on transformer.

(Do not force the insert to start into tapped hole.)

Hold switch down until insert is completely installed and mandrel has

withdrawn fully from insert. (Tool will reverse automatically when set

torque has been reached.)

NOTE:

Check for excessive torque if premature tang breakoff or accelerated

mandrel wear is experienced.

If insert does not completely install (hangs up), the tool should be

checked for low torque, or the mandrel should be checked for damaged

or worn tip.

Width Depth Height

Hole Preparation:

1. Locate and drill hole to required depth with drill size specified.

2. Countersink hole.

3. Tap hole (gage hole occasionally to check for tap wear.)

Depth Stop Setting:

1. Back off lock nut from adjusting collar.

2. Place insert firmly on mandrel with tang engaged on tip.

3. Locate adjusting collar to 1 to 1

/2 pitches from top

end of insert.

4. Tighten lock nut against adjusting collar.

Tang Break-off Tools are for use with 1, 1

and 2 diameter

length inserts. For 2

and 3 diameter, a separate punch

must be ordered with each tool. To order these sizes, add

-30 to end of part number. Replacement punches can be

ordered by putting an “RP” at the end of the part number.

Example: CAB-02RP.

Use standard needle nose pliers to remove tangs on insert

sizes above 1/2 inch. Bend tang up and down to snap off at

notch.

Extracting Tool Instructions: Apply the tool to installed insert

90˚ from the end. Strike the head of the tool lightly with a

hammer. Turn the tool counterclockwise while maintaining a

steady downward pressure.

- Thread Repair Kits

Screw Thread Inserts for Maintenance, Repair and Overhaul

Thread repair using CoilThread

Inserts is a universally accepted method of repairing stripped threads in all types of

metals. Damaged threads can be brought back to the original thread size, and be better than new using stainless steel

inserts. Thread wear, corrosion and galling will be virtually eliminated, and the assembly will be stronger than the

original with CoilThread

Unlike threaded solid bushing type fasteners, CoilThread

Inserts provide space and weight savings to your repair

process. In addition, they eliminate the need for oversized drilling and tapping, and welding or plugging of damaged

holes. At Kato, there is only one standard of quality for original equipment or repair inserts - All CoilThread

Inserts

meet or exceed all applicable military, aerospace and commercial standards.

Each individual thread size Kato-Kit

comes with the following:
