Perma-Coil Thread Repair Kits are the ideal way to repair stripped or damaged threads. Simply drill out the damaged threads, tap the new hole with the special tap provided in the kit, and insert the stainless steel coil using the installation tool provided. The resulting repair is actually stronger than the original threads! Install Perma-Coil inserts in new castings to prevent problems before they start. Perma-Coils are completely interchangeable with Heli-Coil® inserts and tooling. Each kit includes a special tap, an installation tool, and inserts in the quantity indicated. We also stock extra Perma-Coil Insert Packs (Part No. 3868), Replacement Perma-Coil Installation Tools (Part No. 3866), and Replacement Perma-Coil Taps (Part No. 3867).

Also Available: Metric Perma-Coil Thread Repair Kits (Part No. 3870).
