Keep threads sharp and clean to prevent power transmission components from shifting on shafts and spindles. To maintain strong connections, repair worn or damaged threads as well as clear built-up locking compound. Don’t risk damaging threads further with an inferior quality die. Our dies are machined in the U.S. to precise dimensions for a perfect thread profile. They are sized according to the American Bearing Manufacturer's Association (ABMA). Turn dies with a standard adjustable wrench.

Use a single set for many sizes of internal and external threads. The taps and dies are for use on most metal and plastic.

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.
