More Info on Murray Corporation

The Murray Corporation patented split thread repair die is positioned below the damage on your bolt or stud and turning it counterclockwise with a 6 point deep well socket, you restore the threads without cross threading, and faster than conventional thread repair tools.  Made of hardened carbon steel.

Our TriGage tool measures bolt diameter, thread pitch and bolt grade. It also indicates the correct size wrench to use for installing replacement bolts and studs. Don't carry all of your tools, just the ones you need. The TriGage also complements the Split Die Thread Repair Tool to help select the correct size die when repairing damaged bolts and studs. Made of durable stainless steel.

Standard and Metric sizes available.
