Vermont Gage 111215700 Class Zz Minus Plug Pin Gage 0.157in

Product Description

The VERMONT GAGE 111215700 is a Class ZZ minus plug pin gage designed for precision dimensional inspection. It measures 0.1570 inches in diameter and carries a tolerance of 0.0002 inches, making it suitable for NoGo inspection applications where confirming an upper dimensional limit is required. The gage is machined from steel with a 10 microfinish surface coating for consistent, repeatable contact. Each unit ships with a Certificate of Accuracy with NIST traceability, confirming it meets the stated tolerance class. Quality control technicians, machinists, and metrologists use this type of gage in production and inspection environments where tight bore or hole tolerances must be verified.

This plug pin gage is used in manufacturing and quality control settings to inspect drilled, reamed, or broached holes and bores. Its 0.1570-inch diameter and Class ZZ minus classification make it appropriate for NoGo inspection functions, as well as for setting and verifying micrometers, verniers, and other measuring devices. It is sized for light industrial and precision machining applications where consistent go or no-go gauging is part of standard quality workflow.

Key Features

• Class ZZ minus tolerance rating — suited for NoGo inspection and measuring device calibration
• 0.1570-inch measurement diameter with 0.0002-inch tolerance
• Steel construction with 10 microfinish surface coating for accurate contact geometry
• Includes Certificate of Accuracy with NIST traceability
• 2-inch overall length for standard hand-held gauging use

Compatibility

Designed for use in NoGo inspection applications and for setting micrometers, verniers, and other measuring devices requiring a 0.1570-inch reference diameter.

Installation Notes

Plug pin gages are handled and used by quality control technicians and machinists in inspection environments. Keep the gage clean and lightly oiled when not in use to prevent corrosion on the steel surface. Do not force the gage into a bore — contact should be smooth and controlled to avoid damage to either the gage or the workpiece. Store in a protective case away from temperature extremes to maintain dimensional stability.
