Tap, Die, and Thread File Sets

Repair screw threads in a wide range of sizes. The dies are hex shaped for use with conventional wrenches. The taps have a square shank that's compatible with tap wrenches and tap holders for drill presses and drilling machines. With a plug chamfer, all taps have 3-5 chamfered threads and are suitable for thread repair in both through holes and closed-end holes.

Thread-Repairing Die Nut Sets

The dies in these sets match the width of hex nuts that are the same thread size, so one tool can turn both. For tight spaces, use with a ratcheting wrench since it requires minimal clearance to turn. Repairing dies remove imperfections and rust so threads engage properly for a strong connection.
