Vermont Gage 112220000 Class Zz Minus Plug Pin Gage 20.00 Mm

Product Description

The VERMONT GAGE 112220000 is a Class ZZ minus plug pin gage used for precision dimensional inspection in machining and manufacturing environments. It measures a nominal diameter of 20.00 mm with a tolerance of 0.00508 mm, making it suitable for NoGo inspection applications where tight dimensional control is required. The gage body is steel construction with a 10 micro coating finish and an overall length of 2 inches. A Certificate of Accuracy with NIST traceability is included. This tool is typically handled by quality control technicians, machinists, and metrology professionals.

This plug pin gage is used in NoGo inspection workflows to verify that a bore or hole does not exceed its maximum allowable size. It is also suitable for setting micrometers, verniers, and other measuring devices to a known reference diameter. Typical applications include incoming inspection, in-process quality checks, and final acceptance testing in precision machining, tooling, and manufacturing facilities. The 20.00 mm diameter targets metric-dimensioned workpieces common in industrial and OEM production environments.

Installation Notes

Plug pin gages are handled by qualified metrology or quality control personnel. Keep the gage clean and lightly oiled when not in use to prevent corrosion on the steel surface. Do not force the gage into a bore. Store the gage in its protective case away from temperature extremes to maintain dimensional stability.
