Thread Taps

Taps, dies, tap wrenches and tap and die sets from Teng Tools, Groz, Gearwrench and Helicoil, in metric and imperial sizes.

Taps cut internal threads and dies cut external threads. A set is the practical choice for maintenance work, because it covers the common sizes along with the wrench and die stock to drive them.

Use a cutting fluid such as Tap Magic, and back the tap off every turn or so to break the chip. For damaged threads rather than new ones, see our thread repair kits.
