Vermont Gage 912200500 Class Zz Minus Plug Pin Gage 0.50mm

Product Description

The VERMONT GAGE 912200500 is a Class ZZ Minus plug pin gage machined from steel with a black oxide finish. It measures 0.50 mm in diameter and carries a tolerance of 0.00508 mm, making it suitable for NoGo inspection work where precise dimensional verification is required. The gage ships with a Certificate of Accuracy that includes NIST traceability, giving quality technicians and metrology labs documented confidence in the measurement standard. Overall length is 2 inches. The black oxide coating provides corrosion resistance without adding meaningful dimensional variation to the gage surface.

This pin gage is used in dimensional inspection applications where a NoGo member is needed to confirm that a hole or bore does not exceed its maximum allowable size. Typical applications include production floor inspection of drilled or reamed holes, setup and verification of micrometers, verniers, and other measuring devices, and metrology lab standards work. It is suited to both light manufacturing and precision machining environments where tight tolerance verification at the sub-millimeter range is routine.

Key Features

• Class ZZ Minus tolerance designation for NoGo inspection use
• 0.50 mm diameter with 0.00508 mm tolerance
• Steel construction with black oxide finish for corrosion resistance
• Certificate of Accuracy included with NIST traceability documentation
• 2 inch overall length for standard pin gage handle compatibility

Compatibility

Designed for NoGo inspection use with micrometers, verniers, and other dimensional measuring devices requiring a Class ZZ Minus plug pin gage at 0.50 mm diameter.

Installation Notes

Pin gages are handled and used by quality technicians and metrology professionals. Keep the gage surface clean and free of debris before use to avoid false readings or surface damage. Store in a protective case away from humidity to preserve the black oxide finish and dimensional integrity. Do not force a NoGo gage into a feature; if resistance is met, the feature is within acceptable tolerance.
