Tri-Gage Combo Tool

The Gorilla Tool is not your ordinary Thread Pitch Gauge.  Not only will it measure thread pitch, it has a Bolt Sizer to measure diameter and a Bolt Grade Chart as well!  Why carry around three separate tools to accurately identify your bolt or measure one aspect without determining the others?  Doesn't make a lot of sense now, does it?  It's time for the old traditional Thread Pitch Gauge to step aside and make way for the new and improved - Gorilla Tool!  Quickly and accurately find the bolt you need and move forward to the next task.
