The All-In-One:  Bolt Sizer - Thread Pitch Gage - Bolt Grade Chart
 
The revolutionary Tri-Gage Combo Tool is a union between the Thread Pitch Gauge and Bolt Sizer.  Originally developed for the United States Armed Forces, it's designed for use under the most extreme combat conditions, where speed, accuracy and durability are essential to survival.

99% STAINLESS STEEL - it's not only rustproof, but virtually indestructible.  Valuable to both the novice and professional, the Tri Gage fits in the palm of your hand.  Only 3 1/2" in length, 1 1/2" wide and 1/2" thick, its slim profile will comfortably slip into your shirt or pants pocket and the predrilled 3/16" hole will allow you to attach the Tri Gage to your tool belt.

It will accurately measure the thread pitch on your bolts and its slim blade design will also indicate the thread pitch on nuts as small as 1/4".  The bolt sizer blades are machine stamped with both the bolt diameter and the correct wrench size needed for installation.  In addition, the back panel has a clearly marked bolt grade chart, a useful aid in identifying the correct bolt hardness, a valuable feature when trying to match materials in the field.

The Tri-Gage Combo Tool is built using center assembly lock screws, ensuring a lifetime of service.  Black oxided tension wheels are ribbed for a firm non-slip grip.  The tension wheels will allow you to easily select the blade you need and slide the others safely back into the tool's frame.

A few of the many applications for this unique tool include Automotive, Industrial, Marine, Mining and Construction.  Whether you're a mechanic, machinist, engineer or do-it-yourselfer, the Tri-Gage Combo Tool should have a spot reserved in your toolbox.  Retire that rusty old thread pitch gauge and step up to American made quality for under $20!

    It was exactly what I was looking for, and the price was reasonable. Can't say much more than that, can I?
