Vermont Gage 111307650 Class Zz Plus Plug Gage 0.0765 in

Product Description

The VERMONT GAGE 111307650 is a Class ZZ Plus plug gage machined from tool steel and designed for precision go inspection of bored, drilled, and reamed holes. With a measurement diameter of 0.0765 inches and a tolerance of 0.0002 inches, this gage delivers the accuracy required when verifying critical bore dimensions in manufacturing and quality control environments. Each unit ships with a Certificate of Accuracy that carries NIST traceability, meeting the documentation requirements of quality management systems. The 10 microfinish surface provides consistent, repeatable contact during measurement. Machinists, quality technicians, and tool-room professionals use this gage as a direct go inspection tool or as a calibration reference for setting micrometers, verniers, and other precision measuring devices.

This plug gage is suited for precision inspection work in machine shops, production facilities, and metrology labs. It is used during in-process and final inspection to confirm that hole diameters fall within specified tolerance ranges. Typical applications include go inspection of close-tolerance bores and as a setting standard for bench-top and hand-held measuring instruments. The compact overall length of 2.0 inches makes it practical for use in confined inspection setups. Inspectors and machinists working to ASME B89.1 standards will find this gage compliant with that specification for gage tolerancing and accuracy.

Compatibility

Designed for go inspection of holes with a nominal diameter of 0.0765 inches. Also suitable for use as a setting reference for micrometers, verniers, and other precision measuring devices, as stated by the manufacturer.

Installation Notes

Plug gages are handled and used by quality technicians and machinists — no power source or utility shutoff is required. Store gages in a protective case away from moisture and abrasive surfaces to prevent corrosion and wear on the tool steel. Apply a light coat of instrument oil when storing for extended periods. Handle the gage by the handle body, not the gage member, to avoid dimensional change from body heat.
