Why carry three tools when you can carry one? The BoltSizeIt 3-in-1 Combination Gauge is the ultimate multi-tasker, engineered to consolidate your most essential measuring tools into one sturdy, lightweight, pocketable unit.

3-in-1 Precision Identification This versatile tool acts as a complete diagnostic center for your fasteners and bits. It combines three distinct functions into a single interface:

Thread Pitch	Unified National Standard Inch #0 to 3/4" Course and Fine & ISO Metric M6 to M16
Rivet Measuring Tool	The ultimate rivet gauge for identifying Pop Rivets and Blind Threaded Inserts.
Bolt & Screw Identifier	Features internally threaded gauges to instantly size bolts and screws both standard and metric.
Drill Bit Gauge	Located on the reverse side, this section acts as both a standard and metric drill and tap gauge. It identifies diameters instantly so you never use the wrong bit for the hole.
Resistant Material	Sturdy plastic construction resists oil, grease, and chemicals.

Workshop Ready Durability Workshops are messy, but your tools shouldn't suffer for it. Unlike others, this gauge is manufactured from high-impact plastic specifically designed to resist water, alcohol, oil, and grease. It remains reliable and readable even in the grimiest environments.
