Rescue mangled threads and return them to like-new condition. By repairing threads, you don’t have to replace the fastener or resize holes. These dies smooth out flaws and remove rust so threads engage properly and connections stay strong. Turn them with a hex die wrench or a standard adjustable wrench.

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.
