Vermont Gage 111193400 Class Zz Plus Plug Gage 0.934 in

Product Description

The VERMONT GAGE 111193400 is a Class ZZ Plus plug gage machined from tool steel for precise go-inspection work. It measures a nominal diameter of 0.934 inches with a tolerance of 0.0002 inches and a surface finish of 10 microinches. The overall length is 2.0 inches, giving technicians a secure, balanced grip during use. Each unit ships with a Certificate of Accuracy backed by NIST traceability, meeting ASME B89.1 standards. This gage is used by quality control technicians, machinists, and metrology professionals who need reliable dimensional verification in production or inspection environments.

This plug gage is suited for go-inspection applications where a 0.934-inch nominal bore or hole diameter must be verified to tight tolerances. Typical use cases include checking machined bores, verifying hole sizes before assembly, and calibrating or confirming the accuracy of set micrometers, verniers, and other measuring devices. It is appropriate for both shop-floor and lab inspection settings where traceable dimensional accuracy is required.

Compatibility

Designed for go-inspection use with set micrometers, verniers, and other measuring devices requiring a 0.934-inch reference standard, per the application data provided by the manufacturer.

Installation Notes

Plug gages are handled and used by trained quality control technicians and machinists. Keep the gage clean and lightly oiled when not in use to prevent corrosion of the tool steel. Do not force the gage into a bore; apply only hand pressure to avoid damaging the gage or the workpiece. Store in the original case or protective sleeve to maintain the calibrated surface finish.
