Vermont Gage 112208420 Class Zz Minus Plug Pin Gage 8.42 Mm

Product Description

The VERMONT GAGE 112208420 is a Class ZZ Minus plug pin gage designed for precision dimensional inspection. This steel pin gage measures 8.42 mm in diameter with a tolerance of 0.00508 mm, making it suitable for NoGo inspection applications where close-tolerance verification is required. The overall length is 2 inches. Each unit ships with a Certificate of Accuracy traceable to NIST, confirming it meets Class ZZ Minus standards. Machinists, quality control technicians, and metrology professionals use this gage to verify bore and hole dimensions on production and inspection floor environments.

This plug pin gage is used in NoGo inspection routines to verify that a hole or bore does not exceed its maximum allowable dimension. It is also compatible with setting and calibrating micrometers, verniers, and other measuring devices. Typical applications include incoming inspection, in-process quality checks, and final inspection on machined components in manufacturing environments. The 10 microfinish surface coating supports consistent, accurate contact with the measured feature.

Installation Notes

Plug pin gages are handled and used by quality technicians and machinists - no installation trade license is required. Handle the gage with clean, dry hands or lint-free gloves to prevent corrosion from skin oils. Store in a protective case away from temperature extremes and contaminants. Do not force the gage into a hole; apply only light, consistent hand pressure during inspection.
