Vermont Gage 111205100 Class Zz Minus Plug Pin Gage 0.051 in

Product Description

The VERMONT GAGE 111205100 is a Class ZZ minus plug pin gage designed to measure hole diameters with a nominal size of 0.0510 inches. Built from steel with a 10 microfinish surface coating, this pin gage is used in NoGo inspection applications where accurate small-bore measurement is required. Each unit ships with a Certificate of Accuracy that carries NIST traceability, confirming the gage meets tolerance requirements of plus or minus 0.0002 inches. Machinists, quality control technicians, and metrologists rely on this type of gage to verify that a hole falls within acceptable dimensional limits during incoming or in-process inspection.

This pin gage is suited for use in manufacturing and quality assurance environments where small-diameter bore inspection is performed. It is used alongside micrometers, verniers, and other measuring devices to validate part conformance. The minus designation indicates the gage is ground to the minus side of tolerance, making it appropriate for NoGo inspection work. Typical applications include checking drilled, reamed, or punched holes in metal and plastic components across precision machining, toolroom, and production settings.

Key Features

• Steel construction with 10 microfinish surface coating for consistent contact
• Includes Certificate of Accuracy with NIST traceability
• 2 inch overall length for hand-held use in standard inspection setups
• Compatible with set micrometers, verniers, and other measuring devices

Compatibility

Designed for use in NoGo inspection applications and for setting micrometers, verniers, and other measuring devices requiring a 0.0510 inch reference diameter.

Installation Notes

Pin gages are handled and used by quality control technicians and machinists in inspection environments. Keep the gage clean and lightly oiled when stored to prevent corrosion on the steel surface. Do not force the gage into a hole; apply light, consistent hand pressure only. Store in a protective case away from temperature extremes to maintain dimensional accuracy and NIST traceability.
