Thread Repair Kit - Metric Series

Brand: Perma-Coil

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. Each kit includes a special tap, an installation tool, and inserts in the quantity indicated. (Note the 14x1.25 kit does not include any inserts.)

We also stock extra Perma-Coil Metric Insert Packs (Part No. 3873), Replacement Metric Perma-Coil Installation Tools (Part No. 3871), and Replacement Metric Perma-Coil Taps (Part No. 3872).
