Vermont Gage 112307650 Class Zz Plus Plug Gage 7.65mm

Product Description

The VERMONT GAGE 112307650 is a Class ZZ Plus cylindrical plug gage machined from tool steel and designed for precise internal diameter inspection. It measures 7.65 mm in diameter with a tolerance of 0.00508 mm, making it suitable for Go inspection workflows where tight dimensional verification is required. The overall length is 2.0000 inches. Each unit ships with a Certificate of Accuracy that carries NIST traceability, giving quality technicians and metrologists documented confidence in the measurement standard. The 10 microfinish surface minimizes wear on the gage and the bore being checked, extending service life in high-cycle inspection environments.

This plug gage is used in machine shops, production facilities, and quality labs where bores, holes, or ID features must be verified to ASME B89.1 standards. It is compatible with Go inspection routines and can be used alongside set micrometers, verniers, and other calibrated measuring devices. Typical users include quality control inspectors, tool-and-die machinists, and metrology technicians working in both job-shop and high-volume manufacturing settings.

Compatibility

Designed for use in Go inspection applications and as a reference standard with set micrometers, verniers, and other calibrated measuring devices per ASME B89.1.

Installation Notes

Plug gages are handled and used by quality technicians and metrologists — no permanent installation is required. Store the gage in its protective case when not in use to prevent surface damage and corrosion. Clean the gage and the bore being checked before use to ensure accurate readings. Avoid dropping or contacting the gage with abrasive surfaces, as any damage to the finish will affect measurement accuracy.
