Threading, tapping and HELICOIL thread inserts to repair a thread

A damaged thread does not always mean replacing the part. This category offers HELICOIL thread inserts and repair kits, taps, dies, drill bits, broken screw extractors and thread gauges to measure the pitch of a bolt.

A HELICOIL insert must match the original thread exactly: diameter and pitch (for example M8 × 1.25). Measure the bolt with a thread gauge first, then pick the kit that includes the drill, tap and installation tool for that size.
