Perma-Thread Helical Coiled Inserts are designed specifically repair defective, stripped or damaged threads quickly and permanently. These inserts are made of diamond shaped stainless steel wire formed into a spiral screw thread coil. They form a thread which is stronger than the original tapped material. The resilient quality of the insert allows it to adjust to eliminate stress concentration. The Perma-Thread® insert restores the hole to its initial size - a bolt or screw of the original size can be used for reassembly. Also available as a complete Perma-Thread Repair Kits each contain inserts, tap and installation tools. Inserts are priced per standard package quantities.
