High quality Wire Thread Repairing Insert

High quality Wire Thread Repairing Insert

Our standard Free Running Wire Thread Insert is produced from Austenitic Stainless Steel wire, which is cold drawn (profiled) to form a diamond-shaped wire. This wire is then helically coiled to produce the Wire Thread Insert. 

Larger in diameter than the tapped hole, the insert is compressed during installation to ensure maximum surface contact between the flanks of the Thread Insert and tapped threads. Once fitted, the action of the radial pressure between the insert’s coils and flanks of the tapped hole holds thread insert in place securely.

The flexibility of our Stainless Steel Wire Thread Inserts enhances load bearing capacity by deflecting the residual forces into a helical direction, which is dispersed into the wall of the tapped hole.
