Vermont Gage 112215120 Class Zz Minus Plug Pin Gage 15.12mm

Product Description

The VERMONT GAGE 112215120 is a Class ZZ Minus plug pin gage designed for precision dimensional inspection. It measures 15.12 mm in diameter with a tolerance of 0.00508 mm, making it suitable for NoGo inspection work where tight measurement accuracy is required. The gage is machined from steel and finished to 10 micro inches for consistent contact surface quality. At 2 inches in overall length, it fits standard pin gage handles and accessories. Each unit ships with a Certificate of Accuracy that carries NIST traceability, supporting quality documentation requirements in calibration and inspection environments.

This plug pin gage is used in dimensional inspection applications including NoGo limit checks, calibration of micrometers, vernier calipers, and other measuring devices. Class ZZ tolerance class is appropriate for less critical inspection work and general-purpose gage calibration. Typical users include quality control technicians, calibration lab personnel, machinists, and tool room inspectors working in manufacturing, job shop, or MRO environments. The NIST-traceable certificate supports ISO and AS9100 quality system requirements where documented gage certification is mandatory.

Compatibility

Designed for use as a NoGo inspection gage and for setting micrometers, verniers, and other precision measuring devices. Compatible with standard plug gage handles sized for the 15.12 mm diameter range.

Installation Notes

Pin gages are handled by metrology and quality control personnel, not field tradespeople. Store the gage in its protective case when not in use to prevent nicks or corrosion that would affect dimensional accuracy. Clean contact surfaces with a lint-free cloth before use. Do not force the gage into a bore; if resistance is felt, verify the bore size and gage condition before proceeding.
