Vermont Gage 111415850 Class Zz Minus Plug Pin Gage 0.1585 in

Product Description

The VERMONT GAGE 111415850 is a Class ZZ minus tolerance plug pin gage machined to a diameter of 0.1585 inches for NoGo inspection applications. Built from steel with a 10 microfinish surface coating, it delivers the dimensional precision required for verifying that a feature does not exceed its maximum material condition limit. Each unit ships with a Certificate of Accuracy with NIST traceability, satisfying documentation requirements in quality-controlled production and inspection environments. The overall length of 2 inches provides a practical handle for manual gauging operations. Machinists, quality technicians, and metrology professionals use this gage as a reliable go/no-go reference in both shop-floor and laboratory settings.

This plug pin gage is suited for NoGo inspection tasks in manufacturing, toolroom, and quality assurance environments. It is also used to set and verify micrometers, verniers, and other measuring devices requiring a traceable dimensional reference. Typical applications include hole acceptance testing on precision machined parts where tolerance control is critical. The Class ZZ designation indicates a commercial-grade tolerance suitable for general inspection rather than master or working gage applications requiring tighter classifications.

Compatibility

Designed for use in NoGo inspection operations and as a reference standard for setting micrometers, verniers, and other precision measuring devices requiring a traceable dimensional reference at 0.1585 inches.

Installation Notes

Plug pin gages are handled and used by quality technicians and machinists — no mechanical installation is required. Store the gage in its protective case when not in use to prevent surface damage or corrosion that could affect accuracy. Clean contact surfaces with a lint-free cloth before each use. Do not force the gage into a feature; excessive insertion force can damage both the gage and the part under inspection.
