Recoil 25023 M2 Metric Coarse FR Insert 2mm x 0.4 Pitch x 1.5D (Pack of 10)

Recoil helically wound wire thread inserts can be used to strengthen threads, giving applications a longer life. They are rolled from high quality stainless steel wire and cold-drawn into a diamond shaped cross section, formed to the shape of a spring thread. Once the wire is formed into a helical coil insert and installed into a tapped hole, it provides a permanent and wear resistant thread in the parent material that is stronger than the original thread.

The inserts are designed to be greater in diameter than the 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 insert’s 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.

Standard inserts are free-running, but screw-locking inserts are also available.

Use drill size 2.1mm.
