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. By following the detailed instructions enclosed in every PERMA-COIL® kit, even an inexperienced do-it-yourselfer can repair stripped threads, permanently.
