Thread repair inserts are formed from high-quality stainless-steel wire with a diamond-shaped cross-section, wound to the shape of a spring thread. They provide a permanent and wear-resistant thread in the parent material that is generally stronger than the original thread. The inserts are designed to be greater in diameter than the tapped hole and compress as they are installed.

RS offer a selection of thread repair inserts from industry-leading brands including Bollhoff, Recoil, Keenserts, and of course RS PRO. Our fastenings are available in a variety of thread sizes, drill sizes, and thread lengths to suit every repair application.

### How do you install it?

**Drill**

Drill to clear out the damaged thread id required.

**Tap**

Use a thread insert tap to match the size of the bolt.

**Install**

Wind insert in with light downward pressure until 1/4 to 1/2 turn below the surface, driving tang towards the bottom of the hole.

**Remove Tang**

Remove tool and sit back on top of the tang. Tap down sharply. Do not try to twist tang off. For sparkplug and large fine thread inserts, use long-nose pliers and pull tang out.
