| Kit contains inserts, installation tool and tap. Perma-Coil helically coiled inserts are made of stainless steel wire that has been rolled to a carefully controlled thread form. When installed, the insert adjusts to the tapped hole, becoming a functional thread with a strength exceeding the original.
Perma-Coil inserts are designed to repair stripped threads in a variety of metals -- aluminum, aluminum alloys, steel and cast iron. If the original threads can be stripped, Perma-Coil inserts can repair them. |
