RECOIL™s Spark Plug thread repair kits enable you to carry out fast and efficient repair of damaged or stripped threads.

RECOIL™ inserts are rolled from high quality stainless steel wire with a diamond shaped cross section, wound to the shape of a spring thread.
Once the insert is installed into a tapped hole, it provides a permanent and wear resistant thread in the parent material designed to be stronger than the original thread.

The inserts are greater in diameter than the corresponding tapped hole and compress as they are installed.
This allows maximum surface contact area with the tapped thread, safely and permanently anchoring the inserts into place.

The inserts compensatory action shares the load over the entire bolt and hole, increasing holding or pull out strength.
With a RECOIL™ insert in place, load and stress are more evenly distributed.
