Vermont Gage 111279400 Class Zz Minus Plug Gage 0.7940 in

Product Description

The VERMONT GAGE 111279400 is a Class ZZ Minus plug pin gage designed for NoGo inspection applications. This single-ended pin gage measures 0.7940 inches in diameter with a tolerance of 0.0002 inches and an overall length of 2 inches. Manufactured from steel, it delivers the dimensional accuracy required for go/nogo gauging routines in quality control and metrology environments. Each unit ships with a Certificate of Accuracy with NIST Traceability, confirming that the gage meets the dimensional standards required for reliable measurement validation. Machinists, quality technicians, and tool room personnel rely on this type of gage to verify bore and hole sizes against specified tolerances.

This gage is intended for use in NoGo inspection workflows where a precise diameter reference is needed. It is also suitable for setting and verifying micrometers, verniers, and other measuring devices that require a calibrated reference standard. Applications span precision machining, manufacturing quality control, toolroom calibration setups, and incoming inspection stations. The compact 2-inch overall length makes it easy to handle and store in standard gage sets or individual gage blocks.

Installation Notes

Plug pin gages are handled and used by quality technicians and machinists in controlled measurement environments. Store the gage in its protective case and apply a light coat of rust-preventive oil when not in use to preserve surface finish and dimensional integrity. Always clean the gage and the part being measured before gauging to avoid false readings caused by debris or burrs. Do not force the gage into a bore, as this can damage both the gage and the workpiece.
