Vermont Gage 111299700 Class Zz Minus Plug Pin Gage 0.9970 in

Product Description

The VERMONT GAGE 111299700 is a Class ZZ minus plug pin gage ground to a nominal diameter of 0.9970 inches with a tolerance of 0.0002 inches. It is used to verify that a hole or bore does not exceed its maximum allowable size, making it a NoGo inspection gage. The overall length is 2 inches. Constructed from steel, this gage is designed for dimensional inspection in machine shops, manufacturing facilities, and quality control environments. Each unit ships with a Certificate of Accuracy traceable to NIST standards, confirming the gage meets documented dimensional requirements at the time of manufacture.

This plug pin gage is suited for NoGo go inspection routines where a bore or hole must be verified against a maximum material condition limit. It is also used to calibrate or verify setting micrometers, verniers, and other precision measuring devices. Typical applications include incoming inspection, in-process quality control, and final inspection of machined parts in precision manufacturing, toolroom, and metrology lab settings. The minus designation indicates the gage is manufactured to the lower half of the tolerance band, which is standard for NoGo members in two-gage inspection sets.

Key Features

Compatibility

Designed for use as a NoGo inspection gage and as a setting standard for micrometers, verniers, and other precision measuring devices requiring a 0.9970-inch reference diameter.

Installation Notes

Plug pin gages are handled and used by metrology technicians, quality control inspectors, and toolroom machinists. No power source or special tools are required for use. Store gages in a protective case away from temperature extremes and humidity to maintain dimensional stability and prevent corrosion. Apply a light coat of instrument oil when storing for extended periods to protect the steel surface.
