Vermont Gage 111421450 Class Zz Minus Plug Pin Gage 0.2145 in

Product Description

The VERMONT GAGE 111421450 is a Class ZZ Minus plug pin gage machined from steel and used to perform NoGo inspection checks in precision measurement applications. The gage measures 0.2145 inches in diameter with a tolerance of 0.0002 inches and an overall length of 2 inches. Each unit ships with a Certificate of Accuracy traceable to NIST, confirming dimensional compliance at the time of manufacture. Machinists, quality control technicians, and metrology professionals use this type of gage to verify that a hole or bore does not exceed its maximum allowable material condition, ensuring parts meet tight dimensional tolerances before assembly or shipment.

This plug pin gage is suited for use in machine shops, manufacturing facilities, and quality labs where NoGo hole inspection is required. It is also compatible with setting micrometers, verniers, and other measuring devices that require a traceable reference standard. The Class ZZ designation indicates general-purpose inspection tolerances appropriate for production-floor go/no-go gauging workflows. The 10 microfinish surface coating supports consistent gage contact and extended service life in repetitive inspection environments.

Compatibility

Designed for NoGo hole inspection and for setting micrometers, verniers, and other precision measuring devices requiring a traceable dimensional reference.

Installation Notes

Plug pin gages are handled and used by machinists and quality technicians and require no permanent installation. Store the gage in its protective case when not in use to prevent corrosion and surface damage. Clean contact surfaces before each use to avoid false readings caused by debris or burrs. Do not force the gage into a bore — any resistance indicates the feature is at or below the minimum allowable size.
