Stripped & Fixed

When threads become stripped, worn or

damaged for any

reason, the

strength and

reliability are

greatly reduced.

Potentially

dangerous

situations are

eliminated when

the damaged

thread is repaired

with Heli-Coil inserts. The Heli-Coil

threaded insert provides stronger, more

reliable threads than the original tapped

hole and at the same time eliminates the

possibility of thread wear, corrosion,

galling, seizing and rust.

Heli-Coil has the most effective and

niversally accepted method of thread

repair. Heli-Coil inserts quickly and

permanently restore stripped, worn

or damaged threads to their original

size and condition.

The inserts work in just

about any part or material;

aluminum, magnesium,

cast iron, bronze, etc.

The use of light weight

(and soft) materials in fuel

efficient cars means more

thread damage… there is

a Heli-Coil insert to repair

virtually every application.

Damaged threads can be restored to

better than new condition in spark plug

ports, carburetor fuel inlets, transmission

housings, oil drain plugs, exhaust

and intake manifolds, head bolt holes, brake

calipers and more!

The Heli-Coil system makes all other thread

epair methods basically obsolete: welding,

plugging, oversized fasteners and oversized

drilling of mating parts. It’s faster – you

save time, increase your shop’s repair

capabilities and restore parts

hat otherwise would

have to be scrapped.

Heli-Coil repairs

are available in the

following standard

thread series and size

ranges: Inch Coarse

(#8 thru 1-1/2), Inch

Fine (#10 thru 1-1/2),

Metric Coarse (M3 thru

M20), Metric Fine (M8 thru

M18), Spark Plug (10mm, 12mm, 14mm,

18mm & 7/8"), and Pipe Thread

(1/8" thru 1").

In addition to the above, custom sizes

are available for various repairs.

Heli-Coil Stainless

Steel Inserts

eli-Coil inserts are precision formed

oils of extremely hard stainless steel

(18-8) diamond- shaped

wire. When installed

into a Heli-Coil tapped

hole, the insert

provides permanent

conventional screw

threads. The insert has

a driving “tang” for

installation which is

notched for easy

removal.

Thread Repair System

Installation

Drill

Drill out the damaged

threads using the drill

size specified on the kit

or set. Drill to sufficient

depth to accommodate

the insert length

and bolt or screw

being used

Tap

Use the Heli-Coil tap

supplied in the kit or set.

Check the size on the

shank to make sure

you have the right one.

Tap the hole to sufficient

depth to accommodate

the insert length

and bolt or screw

being used.

Install

Use the installation tool

supplied in the kit or set.

Just wind the insert into

the hole until the top coil

is 1/4 - 1/2 turn into the

tapped thread. Now you're

back to the original size

and the original size

fastener can be used.

Tang Removal

The tang must be removed to allow full

passage of the bolt or screw through the

insert. Place square (unchamfered) end of

a punch on the tang and strike sharply.

For inserts over 1/2", M14 and up, and

all spark plug sizes, use long nose pliers.

Holding the tang with the pliers, bend it

alternately in and out until it comes free.

Note: For Spark Plug repairs, NO

drilling is necessary. The Heli-Coil spark

plug kit contains a piloted reamer tap.

With this tap, the damaged threads are

removed and new threads are cut in one

continuous operation.

The Retention Principle

Heli-Coil inserts are

larger in diameter

before installation

than the tapped hole.

During installation,

the inserting tool

reduces the diameter

of the leading coil so

it can enter the

tapped hole. After the installation, each

high tensile stainless steel coil expands

outward against the tapped hole to

permanently anchor the insert.
