Perma-Coil Inserts & Thread Repair Kits at Global Auto Parts
Perma-Coil helically coiled inserts are made from premium quality 18-8 stainless steel, rolled to a precisely controlled diamond shape thread form. Slightly oversized in diameter, when installed into a STI (Screw Thread Insert) tapped hole, the insert expands outward with a spring-like action that securely grips the wall of the parent material. The result is a much stronger, permanent thread.
Perma-Coil inserts and repair kits are designed to repair stripped threads in a variety of metals including aluminum, aluminum alloys, magnesium, cast iron and bronze. If the original threads can be stripped, there is a Perma-Coil insert to repair it. Perma-Coil repair kits are available in the following standard thread sizes: Inch Coarse (4-40 thru 1 ½), Inch Fine (10-32 thru 1 ½), Metric Coarse (M3 thru M20), Metric Fine (M8 thru M16), Spark Plug (10mm, 12mm, 14mm & 18mm) and Pipe Thread (1/8” thru 1”).
We carry a selection of both Inch Series repair kits and packaged inserts, Metric Series repair kits and packaged inserts, as well as the wire and solid type Spark Plug thread repair kits and inserts.
