Murray Tools Split Die Thread Repair System

Murray Tools Split Die Thread Repair System

The Murray Tools Split Die thread repair system is designed to save you time and money. Because our hex dies are split and utilize our special spring design, you can place our metric and standard thread dies below the damages on your bolt or stud, then using a 6 point deep well socket, chase the threads clean. Our patented system is fast and easy to use, and because you start on clean, undamaged threads, you avoid cross threading.

Our dies come in National Coarse, National Fine and Metric. We offer hex dies for the following sizes of bolts and studs:

Standard Thread Repair
1/4”, 5/16”, 3/8”, 7/16”, ½”, 9/16”, 5/8”, ¾”, 7/8”, 1”
