Vermont Gage 111425950 Class Zz Minus Plug Pin Gage 0.2595 in

Product Description

The VERMONT GAGE 111425950 is a Class ZZ Minus plug pin gage machined to a 0.2595-inch diameter for precision dimensional inspection work. This single-ended pin gage is designed to verify the NoGo condition in hole and bore inspection, confirming that a feature does not exceed its maximum material condition limit. Built from steel with a 10 microfinish surface coating, it delivers the surface quality required for accurate, repeatable gauging. Each unit ships with a Certificate of Accuracy traceable to NIST, making it suitable for use in calibrated inspection environments. The overall length is 2 inches, and the tolerance is held to 0.0002 inches.

This pin gage is used in manufacturing, machining, and quality-control settings where hole-diameter verification is required. It is suited for NoGo inspection checks as well as for setting and verifying micrometers, verniers, and other measuring instruments. Typical users include machinists, quality technicians, and metrology professionals working to close-tolerance specifications in production or inspection environments. The Class ZZ designation places this gage in the standard commercial tolerance class for general workshop and inspection use.

Compatibility

Designed for use as a NoGo plug pin gage and for setting micrometers, verniers, and other measuring devices requiring a certified 0.2595-inch reference diameter.

Installation Notes

Pin gages should be handled by metrology or quality personnel following standard gage-handling practices. Clean the gage and the feature being inspected before use to prevent contamination from affecting measurement accuracy. Do not force the gage into a feature — light, consistent hand pressure is the correct technique for plug gage inspection. Store in a protective case away from temperature extremes to maintain dimensional stability.
