Vermont Gage 111423950 Class Zz Minus Plug Pin Gage 0.2395 in

Product Description

The VERMONT GAGE 111423950 is a Class ZZ minus-tolerance plug pin gage ground to a nominal diameter of 0.2395 inches with a tolerance of 0.0002 inches. The part measures 2 inches in overall length and is machined from steel with a 10 microfinish surface coating. Plug pin gages in the Class ZZ minus configuration are used as NoGo members in go/no-go inspection routines, confirming that a hole or bore does not exceed its maximum allowable size. Each unit ships with a Certificate of Accuracy that carries NIST traceability, satisfying most quality-system audit requirements.

This gage is suited for dimensional inspection in machine shops, manufacturing facilities, and tool rooms where bore and hole tolerances must be verified to close standards. The 0.2395-inch diameter targets holes in that specific nominal range. Beyond NoGo bore inspection, the manufacturer lists compatibility with setting micrometers, verniers, and other precision measuring devices that require a traceable reference standard for zeroing or calibration checks. It is appropriate for both production-floor inspection stations and metrology lab use.

Key Features

• Class ZZ minus tolerance: 0.0002 inches, suitable for NoGo inspection applications
• Nominal diameter of 0.2395 inches for precise bore and hole verification
• Steel construction with 10 microfinish surface coating for dimensional stability and wear resistance
• Overall length of 2 inches for standard pin gage handling and fixture compatibility
• Includes Certificate of Accuracy with NIST traceability for quality-system compliance
• Also functions as a reference standard for setting micrometers, verniers, and similar measuring devices

Compatibility

Designed for NoGo bore and hole inspection and for setting micrometers, verniers, and other precision measuring devices, as stated by the manufacturer. Verify nominal diameter requirement before use.

Installation Notes

Pin gages are handled and used by quality technicians, machinists, and metrologists. Clean the gage and the bore or measuring device contact surfaces before use to prevent false readings from debris or residual cutting fluid. Apply light gage oil during storage to protect the steel surface from corrosion. Never force a plug gage into an undersized hole; entry should be by gravity or light hand pressure only.
