Vermont Gage 112212420 Class Zz Minus Plug Pin Gage

Product Description

The VERMONT GAGE 112212420 is a Class ZZ Minus plug pin gage used to perform NoGo inspection of bored, drilled, and reamed holes. It measures 12.42 mm in diameter with a tolerance of 0.00508 mm, making it suitable for high-accuracy dimensional verification on the shop floor or in a quality lab. The gage is machined from steel and finished to a 10 microfinish surface for consistent, repeatable contact. It ships with a Certificate of Accuracy that includes NIST traceability, satisfying most quality management and audit requirements. Machinists, quality technicians, and inspection personnel use this tool as part of a complete go/nogo gage set or alongside micrometers, verniers, and other precision measuring devices.

This pin gage is intended for NoGo hole inspection in precision machining environments, including manufacturing floors, tool rooms, and quality control departments. It is appropriate for both production inspection and calibration support work. The gage is also suited for setting micrometers, verniers, and similar measuring instruments that require a known reference diameter. At 2 inches in overall length, it fits standard gage handle holders used throughout the industry.

Installation Notes

Pin gages are handled and stored by quality technicians and toolroom personnel following standard metrology practices. Keep the gage clean and lightly oiled when not in use to prevent corrosion on the steel surface. Never force the gage into a hole; apply only light hand pressure to avoid damaging the gage or the workpiece. Store in a protective case away from abrasive materials and temperature extremes to maintain dimensional integrity.
