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.
