Vermont Gage 112407570 Class Zz Minus Plug Pin Gage 7.57mm

Product Description

The VERMONT GAGE 112407570 is a Class ZZ Minus plug pin gage manufactured from steel for precision dimensional inspection. It measures 7.57 mm in diameter with a tolerance of 0.00508 mm, making it suited for NoGo inspection applications where tight measurement control is required. The gage has an overall length of 2 inches and carries a Certificate of Accuracy with NIST traceability, confirming its calibration to a national standard. Machinists, quality control technicians, and metrology professionals use pin gages like this one to verify hole diameters and check the fit of precision bores in production and inspection environments.

This plug pin gage is designed for use in NoGo inspection routines as well as for setting and verifying micrometers, verniers, and other measuring devices. It is appropriate for both shop-floor and laboratory metrology applications where repeatable, traceable dimensional verification is required. The 10 microfinish surface coating supports accurate contact measurement and reduces wear during repeated use. This gage is suitable for light industrial, toolroom, and quality assurance settings wherever precise hole and bore diameter verification is performed.

Compatibility

Designed for use in NoGo hole inspection routines and for setting micrometers, verniers, and other precision measuring devices requiring a 7.57 mm reference diameter.

Installation Notes

Pin gages are handled and used by quality control technicians and machinists; no installation in the traditional sense applies, but proper handling practice is required to maintain accuracy. Always clean the gage and mating bore with a lint-free cloth before use to prevent contamination from affecting readings. Store the gage in its protective case when not in use to prevent surface damage that could affect the 10 microfinish coating. Do not force the gage into a bore; if resistance is met, check for burrs or debris before proceeding.
