Thread Repair Inserts

Threaded inserts are formed from high quality stainless steel wire with a diamond shaped cross section, wound to the shape of a spring thread. They provide a permanent and wear resistant thread in the parent material that is generally stronger than the original thread. The inserts are designed to be greater in diameter than the tapped hole and compress as they are installed.
