Vermont Gage 111422750 Class Zz Minus Plug Pin Gage 0.2275 in

Product Description

The VERMONT GAGE 111422750 is a Class ZZ Minus plug pin gage designed for NoGo inspection applications in precision measurement work. Machined from steel with a 10 microfinish coating, this pin gage measures a nominal diameter of 0.2275 inches with a tolerance of 0.0002 inches. The overall length is 2 inches, making it a compact, single-pin gage suited for use in quality control environments. Each unit ships with a Certificate of Accuracy backed by NIST traceability, confirming dimensional compliance at time of manufacture. Machinists, quality technicians, and metrologists rely on this gage to verify that a hole or bore does not exceed its maximum allowable limit.

This pin gage is used in manufacturing, job shop, and inspection room settings where precise bore verification is required. Class ZZ Minus designation indicates it is ground to the minus tolerance side of the nominal diameter, making it appropriate for NoGo gauging per standard inspection practice. It is also suitable for setting and verifying micrometers, verniers, and other measuring devices where a certified reference standard of this diameter is needed. Typical users include quality control inspectors, tool and die makers, and CNC machine operators performing in-process or final inspection checks.

Key Features

• Class ZZ Minus tolerance ground to 0.0002 inches for NoGo inspection use
• Nominal diameter of 0.2275 inches with 10 microfinish surface coating

• Suitable for setting micrometers, verniers, and other measuring instruments

Compatibility

Designed for use as a NoGo plug gage in standard bore inspection workflows and as a reference standard for setting and verifying micrometers, verniers, and comparable dimensional measuring devices requiring a 0.2275-inch certified pin reference.

Installation Notes

Pin gages are handled and used by quality technicians and metrologists in inspection environments. Store the gage in its protective case when not in use to prevent surface damage that could affect dimensional accuracy. Clean contact surfaces with a lint-free cloth and appropriate solvent before use to remove oils or debris. Do not force the pin into a bore; excessive insertion force can damage both the gage and the workpiece.
