  FEATURES & APPLICATIONS

Thread Inserts are the quick and easy method for repairing damaged threads, or creating stronger original threads in alloys and composite materials in original equipment manufacture.

Simplifies changeover from unified to metric and vice versa.

bullet

Reduces thread wear.

bullet

Wide temperature tolerance.

This versatility makes Thread Inserts suitable for a wide range of applications.

Thread Insert repair kits help prevent costly machine downtime Range Kits, a multiple size kit format, are widely used in maintenance workshops.

 

  TYPES OF THREAD INSERTS

....... are available in two basic types 

 

bullet

Standard      : Provides a free running thread
 

bullet

Screw Lock : Provides an exclusive resilient internal locking thread
 


  INSTALLATION PROCEDURE

.... different point types and their uses    

Very often you will find a set screw application where you can't use a locking point or even a cup point. This is where you would be familiar with the other standard wet screw point styles and their particular uses. We have listed there point styles and typical uses here for you to make the right choices.

DRILLING:

Use regular drilling procedures to diameter specified in the catalogue for different threads

TAPPING:

Tapping is usually done in a single operation with one of the type of special finishing taps or rough taps as the application demands

 

GAUGING:

Cleaning of tapped hole is done using our special thread gauge, also to check size and full thread depth in conventional manner

 

INSTALLING INSERTS:

Prewinder Type Inserting tools are available for hand installation of inserts. It is a precision tool which aligns and recompresses and the inserts for easy installation. A slotted mandrel in the tool drives the insert by its tang. This tool is recommended for hand installation of all sizes of Coarse & Fine series inserts.

REMOVING INSERT TANGS:

The tang on a Insert should be removed after installation only when necessary for screw clearance or product appearance, and in such cases notched insert should be used. This is easily accomplished by placing the punch of the tang break off tool into the installed inserts and resulting tool squarely on the insert tang. Strike the top of the tool with a hammer, using a sharp blow.

EXTRACTING INSERTS:

At instances when inserts are to be removed, it can be done using Extracting Tool which in available in different sizes. Place the blade of the extracting tool into inserts as shown. Hit the top of the tool with hammer, causing the blade to bite into the insert. Push down on the tool and rotate counter clockwise to back the inserrs of the hole.
