Vermont Gage 112206320 Class Zz Minus Plug Pin Gage 6.32 Mm

Product Description

The VERMONT GAGE 112206320 is a Class ZZ minus plug pin gage with a 6.32 mm measurement diameter, designed for precision dimensional inspection work. This single-end pin gage is configured as a NoGo member, used to verify that a bored or reamed hole does not exceed its maximum allowable size. Manufactured from steel with a 10 microfinish surface coating, it holds a tolerance of 0.00508 mm. Overall length is 2 inches. Each unit ships with a Certificate of Accuracy traceable to NIST standards, making it suitable for calibrated inspection environments and quality control documentation requirements.

This pin gage is used in metrology and quality inspection applications across manufacturing, machining, and tooling environments. The NoGo configuration is employed to reject out-of-tolerance holes during in-process or final inspection. It is compatible with standard gage handle holders and is appropriate for use alongside set micrometers, verniers, and other precision measuring devices. Typical users include machinists, quality control technicians, and tool and die professionals working to tight dimensional specifications.

Compatibility

Designed for use with standard plug gage handles and compatible with set micrometers, verniers, and other precision measuring devices as noted by the manufacturer. Intended for NoGo inspection of holes at the 6.32 mm nominal diameter.

Installation Notes

Pin gages are handled and stored by metrology or quality control personnel, not field trade installers. Always handle pin gages with clean, dry gloves or a lint-free cloth to prevent corrosion from skin oils. Store in the original case or a protective sleeve when not in use. Do not force a pin gage into a hole - controlled, light hand pressure is the correct technique to avoid damaging the gage or the workpiece surface.
