Murray Tools Tri Gage Combo Tool

Bolt Sizer - Thread Pitch Gage - Bolt Grade Chart

Bolt Sizers & Thread Pitch Gauges

The Murray Tools Tri Gage Combo Tool is ideal for mechanics, machinists, engineers and do-it-yourselfers. Our time saving tool is a combination Bolt Sizer and Thread Pitch Gage and adds a Bolt Grade Chart, for accurate replacement of bolts. It is also a complement to the Murray Tools Thread Repair System.  When repairing damaged fasteners, use the Tri Gage tool to measure the diameter and thread pitch, then select the correct size thread repair die to chase your threads clean. 

Please click (here) to see our video demonstration of the bolt sizer thread pitch gage.

If repair is not an option, and the fastener must be replaced, then the Tri Gage tool can help you measure and properly select the correct size replacement bolt. The Bolt Sizer also indicates the correct wrench size to use to install the bolt.
