Rotate these dies around studs and rods to create new fastener threads. A cut above lower-quality dies that can leave inferior threads, these are machined in the U.S. to precise dimensions for accuracy and consistency.

They are adjustable, so you can cut a shallow thread that makes it easier to get the die started on the first pass. Turn the set screw to open the die to its largest diameter. Then rotate the die with a round die wrench and adjust the screw as you make additional passes to reach the proper thread size.

If your wrench can turn a hex nut, it can turn these dies. They match the width of nuts of the same thread size, so you only need one tool to remove the nut, repair threads on the fastener, and put the nut back on. When space is tight, use dies with a ratcheting wrench since it requires minimal clearance to turn. Repairing dies remove imperfections and rust, resulting in threads that engage properly for a strong connection.

Repair instead of replacing left-hand fasteners, which can be expensive and hard to find. These dies correct flaws and clean out rust so the threads engage properly. 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. Turn them with a hex die wrench or a standard adjustable wrench.
