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.

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.

Make your own threads instead of searching for left-hand fasteners, which can be expensive and hard to find. 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 create 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.

Use these dies with Ridgid pipe threader die heads on Ridgid pipe threaders.
