Vermont Gage 112415710 Class Zz Minus Plug Pin Gage 15.71mm

Product Description

The VERMONT GAGE 112415710 is a Class ZZ Minus plug pin gage designed for precision dimensional inspection in industrial and metrology applications. Machined from steel with a 10 micro-inch finish coating, this pin gage measures 15.71 mm in diameter with a tolerance of 0.00508 mm, meeting Class ZZ minus specifications for NoGo inspection work. At 2 inches in overall length and 0.17 pounds, it is a compact, single-purpose tool that delivers repeatable, traceable measurement results. Each unit ships with a Certificate of Accuracy backed by NIST traceability, making it suitable for quality-controlled environments where documentation is required.

This plug pin gage is used in NoGo inspection routines to verify that a bored or reamed hole does not exceed its maximum allowable diameter. It is also suited for setting and verifying micrometers, verniers, and other measuring devices to a known reference diameter. Typical users include machinists, quality control technicians, and metrology lab personnel working in manufacturing environments where hole tolerance verification is a routine part of the production process.

Installation Notes

Pin gages are installed and used by quality control technicians and machinists; no power source or lockout procedure is required. Insert the pin gage into the appropriate gage handle before use to ensure proper grip and control during inspection. Keep the gage surface clean and free of burrs or debris that could affect measurement accuracy. Store in a protective case away from temperature extremes to maintain calibration integrity.
