Vermont Gage 112222440 Class Zz Minus Plug Pin Gage 22.44 Mm

Product Description

The VERMONT GAGE 112222440 is a Class ZZ Minus plug pin gage machined to a 22.44 mm diameter with a tolerance of 0.00508 mm. It is used for NoGo inspection work in precision measurement applications. The gage is constructed from steel with a 10 micro surface finish and measures 2 inches in overall length. Each unit ships with a Certificate of Accuracy backed by NIST traceability, making it suitable for quality control environments where documented calibration is required. Machinists, quality technicians, and metrology professionals use this type of gage to verify that a feature does not exceed its maximum allowable material condition.

This plug gage is intended for NoGo inspection of bored holes, machined features, and similar dimensional checks in manufacturing and production environments. It is also suited for use alongside set micrometers, verniers, and other precision measuring devices as a reference standard. The Class ZZ designation indicates a commercial-grade tolerance class appropriate for general inspection work. Typical users include quality control personnel in machine shops, toolrooms, and production facilities where repeatable go/nogo gauging is part of the inspection process.

Installation Notes

Plug pin gages are handled and stored by metrology and quality control technicians. Keep the gage clean and lightly oiled when not in use to prevent corrosion on the steel body. Do not force the gage into a feature; improper insertion can damage both the gage and the workpiece. Store in the provided case or a controlled environment to maintain calibration integrity and protect the surface finish.
