Vermont Gage 111405250 Class Zz Minus Plug Pin Gage 0.0525 in

Product Description

The VERMONT GAGE 111405250 is a Class ZZ minus plug pin gage with a 0.0525-inch measurement diameter, designed for NoGo inspection applications in precision metrology. This pin gage is manufactured from steel and delivers a 10 microfinish surface coating for consistent, repeatable contact during gauging. With an overall length of 2 inches and a tolerance of 0.0002 inches, it meets the dimensional control requirements expected on the shop floor and in quality labs. Each unit ships with a Certificate of Accuracy bearing NIST traceability, confirming conformance to Class ZZ minus tolerance standards. Machinists, quality technicians, and tool-and-die professionals rely on these gages for tight-tolerance hole and bore verification.

This pin gage is suited for NoGo inspection routines where verifying maximum material condition is required. It is also used for setting and calibrating micrometers, verniers, and other precision measuring devices. Typical applications include incoming inspection, in-process quality checks, and final verification in manufacturing environments handling small-diameter features. The 0.0525-inch diameter targets fine bores and drilled holes common in precision machined components, instrumentation, and tooling assemblies.

Key Features

• Class ZZ minus tolerance at 0.0002 inches for NoGo inspection use
• 0.0525-inch measurement diameter for small-bore and fine-hole verification
• 10 microfinish surface coating for consistent, repeatable gauging contact
• 2-inch overall length for stable handling during inspection
• Steel construction for durability in shop-floor and lab environments
• Includes Certificate of Accuracy with NIST traceability

Compatibility

Designed as an OEM-style Class ZZ minus plug pin gage for use in standard pin gage sets and holders sized for 0.0525-inch diameter members, and for setting micrometers, verniers, and other compatible precision measuring devices.

Installation Notes

Pin gages are handled and used by quality technicians and machinists; no permanent installation is required. Keep the gage clean and lightly oiled when stored to prevent corrosion on the steel surface. Avoid dropping or forcing the gage into bores, as impact or side-loading can alter the calibrated diameter and invalidate the NIST-traceable certification. Store in a protective case away from temperature extremes to maintain dimensional stability.
