Perma-Coil Thread Repair System
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 each kit), and insert the stainless steel coil using the installation tool (also provided in each kit). The resulting repair is actually stronger than the original threads! Install Perma-Coil inserts in new castings to prevent problems before they start. Kits includes a special tap, a metal installation tool, and inserts in the quantity indicated. Replacement insert packs and tools also available separately.
