About our Thread Repair Inserts
The most effective and universally accepted method of thread repair.
Quickly and permanently restore stripped, worn or damaged threads to their original size and condition.
Work in any type of material.
Stainless steel inserts eliminate thread wear, corrosion, galling and rust.

Note: When measuring a thread repair insert it must be measured IN the hole. Measuring outside the hole will not give an indication of the overall length as the insert is not in its compressed form.
