Recoil® Screw Thread Inserts

The Simple, Cost Effective System for Repairing or Creating Stronger Threads

Why use RECOIL inserts ?

Recoil screw threads inserts are used to produce new threads or can be used to repair threaded holes which have been damaged or stripped and refurnish them to their original thread size.

The Recoil insert, which is larger in diameter than the tapped hole is compressed during installation then allowed go spring back, permanently anchoring the insert in the tapped hole.

Because of the larger diameter, the Recoil insert has a greater contact area and is normally stronger than the original threads

How RECOIL WORKS



Recoil inserts are made from high quality stainless steel wire, with a diamond shaped cross section, wound to the shape of a spring thread. The insert, which is larger in diameter than the tapped holes is compressed during installation then allowed go spring back, permanently anchoring the insert in the tapped hole.



Because of the larger diameter, the Recoil insert has a greater contact area and is normally stronger than the original threads.
