Helically Coiled Inserts & Thread Repair Kits

Perma-Coil helically coiled inserts are made of stainless steel wire that has been rolled to a carefully controlled thread form. When installed, Perma-Coil inserts adjust to a tapped hole, becoming a functional thread with a strength exceeding the original.

Perma-Coil inserts and repair kits are designed to repair stripped threads in a variety of metals, including aluminum, aluminum alloys, steel, and cast iron. If the original threads can be stripped, Perma-Coil inserts can repair them. 
Are you currently using Heli-Coil brand thread inserts?  According to the manufacturer of Perma-Coil inserts, the Perma-Coil inserts are fully interchangeable with Heli-Coil inserts.
