Vermont Gage 111281200 Class Zz Minus Plug Pin Gage 0.812 in

Product Description

The VERMONT GAGE 111281200 is a Class ZZ Minus plug pin gage with a 0.8120-inch diameter, designed for NoGo inspection applications in precision measurement workflows. Built from steel with a 10 micro coating finish, this pin gage delivers a tolerance of 0.0002 inches, making it suitable for verifying that a bored or reamed hole does not exceed its maximum allowable size. Each unit ships with a Certificate of Accuracy with NIST Traceability, confirming calibration chain integrity. At 2 inches overall length, it is a compact, hand-held tool used in both shop floor and quality lab environments.

This pin gage is used in NoGo inspection routines to confirm that hole dimensions remain within specified tolerances. It is also suited for setting micrometers, verniers, and other precision measuring devices requiring a certified reference diameter. Typical applications include incoming inspection, in-process quality checks, and calibration reference tasks across machining, tooling, and general manufacturing environments. Machinists, quality technicians, and metrology professionals are the primary users of this type of gage.

• Class ZZ Minus tolerance classification for NoGo plug gage applications
• 0.8120-inch measurement diameter with 0.0002-inch tolerance
• Steel construction with 10 micro coating finish for wear resistance
• 2-inch overall length for easy one-hand use during inspection
• Includes Certificate of Accuracy with NIST Traceability for calibration chain documentation
• Suitable for setting micrometers, verniers, and other precision measuring instruments

Compatibility

Designed as a NoGo inspection gage for use with Go/NoGo gage sets, and as a setting reference for micrometers, verniers, and comparable precision measuring devices in standard shop and laboratory measurement applications.

Installation Notes

Pin gages are handled and used by quality technicians and machinists following standard metrology practices. Store the gage in its protective case when not in use to prevent burring or surface damage that could affect accuracy. Clean the gage and the workpiece bore before inspection to avoid false readings caused by debris or oil buildup. Do not force the gage into a hole; controlled, light insertion pressure is standard practice.
