Vermont Gage 112307150 Class Zz Plus Plug Gage 7.15mm

Product Description

The VERMONT GAGE 112307150 is a Class ZZ Plus plug gage designed for precise go-inspection of drilled, reamed, or machined holes with a nominal diameter of 7.15 mm. Manufactured from tool steel with a 10 microfinish surface, this gage delivers consistent, repeatable results in shop and inspection environments. Tolerance is held to 0.005 mm, conforming to ASME B89.1 standards. Each unit ships with a Certificate of Accuracy backed by NIST traceability, making it suitable for quality-control documentation requirements. Overall length is 2.0 inches, and the gage weighs 0.04 pounds.

This plug gage is used in manufacturing, machining, and metrology settings where hole diameter must be verified to close tolerance. Typical applications include go inspection of through-holes and blind holes in production parts. It is also compatible with use alongside set micrometers, verniers, and other precision measuring devices for calibration and verification workflows. Suitable for both job-shop and production-floor inspection tasks.

Installation Notes

Plug gages should be handled by qualified inspection or metrology personnel. Keep the gage clean and lightly oiled when not in use to prevent corrosion of the tool steel surface. Do not force the gage into an undersized hole, as this can damage the gage land and affect accuracy. Store in a protective case away from temperature extremes to maintain dimensional stability.
