Vermont Gage 111404050 Class Zz Minus Plug Pin Gage 0.0405 in

Product Description

The VERMONT GAGE 111404050 is a Class ZZ Minus plug pin gage designed for NoGo inspection work in precision measurement applications. This single-end pin gage checks that a hole or bore does not exceed the specified upper tolerance limit. The gage measures 0.0405 inches in diameter and has an overall length of 2 inches. It is manufactured from steel and features a 10 microfinish surface coating for consistent, repeatable contact. Each unit ships with a Certificate of Accuracy that carries NIST traceability, satisfying documentation requirements for controlled inspection environments. Machinists, quality technicians, and tool room professionals use this gage to verify tight-tolerance bores and holes on production and inspection floors.

This pin gage is suited for NoGo inspection of precision-drilled or reamed holes in both production and quality-control settings. It is also used to set micrometers, verniers, and other measuring devices requiring a traceable reference standard. The Class ZZ Minus tolerance designation indicates the gage is manufactured to the minus side of the ZZ tolerance band, making it appropriate for inspection of holes where confirming the maximum material condition is critical. Typical applications include aerospace, automotive, medical device, and general precision machining environments where hole-size verification is part of a documented inspection process.

Compatibility

Designed for use as a NoGo inspection gage and as a setting reference for micrometers, verniers, and other precision measuring devices requiring a traceable diameter standard at 0.0405 inches.

Installation Notes

Pin gages are handled and used by quality technicians and machinists in inspection environments — no power source or mechanical installation is required. Keep the gage clean and lightly oiled when stored to prevent corrosion on the steel surface. Do not force the gage into a hole; proper NoGo inspection technique requires the gage to be inserted with light hand pressure only. Store in a protective case away from temperature extremes to maintain dimensional stability and traceability integrity.
