Vermont Gage 911208100 Class Zz Minus Plug Pin Gage

Product Description

The VERMONT GAGE 911208100 is a Class ZZ Minus plug pin gage designed for dimensional inspection of small-diameter bores and holes. Measuring 0.0810 inches in diameter with a tolerance of 0.0002 inches, this gage serves as a NoGo inspection tool used to verify that a hole or bore does not fall outside the acceptable size limit. Constructed from steel with a black oxide finish, it resists corrosion and maintains dimensional stability under typical shop conditions. Each unit ships with a Certificate of Accuracy traceable to NIST, supporting calibration documentation requirements in quality-controlled environments. Metrology technicians and precision machinists rely on this type of gage daily.

This plug pin gage is suited for use in manufacturing, machining, and quality control environments where precise bore inspection is required. The Class ZZ designation indicates it meets standard commercial-grade tolerance specifications appropriate for general-purpose inspection work. It is also compatible with use alongside set micrometers, verniers, and other calibrated measuring devices when establishing or verifying reference dimensions. The overall length of 2 inches provides adequate handling clearance for most bench and in-process inspection tasks.

Key Features

Compatibility

Designed for NoGo inspection use alongside set micrometers, verniers, and other calibrated measuring devices where a 0.0810 inch diameter reference is required.

Installation Notes

Plug pin gages are handled and used by metrology technicians and quality control inspectors. Store the gage in its protective case when not in use to prevent damage to the precision ground surface. Clean the gage pin and the bore being checked before inspection to ensure accurate readings. Do not force the pin into a bore; excessive force can damage both the gage and the workpiece.
