Vermont Gage 112307630 Class Zz Plus Plug Gage 7.63mm

Product Description

The VERMONT GAGE 112307630 is a Class ZZ Plus plug gage designed for precise dimensional inspection of bore and hole diameters in a machining or quality-control environment. Manufactured from tool steel with a 10 microfinish coating, it checks a nominal diameter of 7.63 mm with a tolerance of 0.00508 mm. The gage measures 2.0000 inches in overall length and weighs approximately 0.04 pounds. Each unit ships with a Certificate of Accuracy that carries full NIST traceability, meeting the requirements of ASME B89.1. Machinists, QC inspectors, and metrology technicians use this gage as part of go inspection routines on production floors and in inspection labs.

This plug gage is suited for go inspection applications where tight bore tolerances must be verified quickly and reliably. It is compatible with standard gage handle holders and integrates into inspection routines alongside set micrometers, verniers, and other precision measuring devices. Typical use cases include production line in-process checks and final inspection of machined components where a 7.63 mm bore diameter is specified.

Compatibility

Designed for use with standard plug gage handles and compatible with set micrometers, verniers, and other precision measuring devices for go inspection of 7.63 mm diameter bores.

Installation Notes

This gage is handled and used by machinists, QC inspectors, and metrology technicians — no power source or tool installation is required. Keep the gage clean and lightly oiled when stored to prevent corrosion of the tool steel body. Allow the gage and the workpiece to reach the same ambient temperature before use to avoid measurement errors caused by thermal expansion. Store in the provided case or a protected environment to maintain the calibrated surface finish.
