Vermont Gage 111307950 Class Zz Plus Plug Gage 0.0795 in

Product Description

The VERMONT GAGE 111307950 is a Class ZZ Plus plug gage designed for precision dimensional inspection of small-diameter bores and holes. Built from tool steel with a 10 microfinish surface, this gage measures 0.0795 inches in diameter with a tolerance of 0.0002 inches. It comes with a Certificate of Accuracy with NIST traceability, making it suitable for quality control environments where documentation is required. Machinists, tool and die makers, and quality technicians use this type of gage to verify hole size quickly and repeatably during production or incoming inspection.

This plug gage is used in go inspection applications, confirming that a hole or bore falls within the acceptable size range. It is also compatible with setting and calibrating micrometers, verniers, and other precision measuring devices. At 2.0 inches in overall length, it is sized for bench use and small-bore applications common in precision machining and manufacturing environments. The Class ZZ Plus designation indicates a tighter tolerance than standard Class ZZ gages, making it appropriate for closer-tolerance work.

Key Features

• Class ZZ Plus tolerance class with 0.0002 inch tolerance for close-tolerance inspection
• 10 microfinish surface for consistent, repeatable contact with bore surfaces
• Includes Certificate of Accuracy with NIST traceability for quality documentation
• Manufactured from tool steel for durability and wear resistance
• Conforms to ASME B89.1 standards for gage accuracy and construction
• Compact 2.0 inch overall length suited for bench and production use

Compatibility

Designed for go inspection of holes and bores measuring 0.0795 inches in diameter. Also suitable for setting micrometers, verniers, and other precision measuring devices requiring a traceable reference standard.

Installation Notes

Plug gages are handled and used by quality technicians and machinists — no power tools or electrical shutoff is required. Keep the gage clean and lightly oiled when not in use to prevent corrosion and maintain the calibrated surface finish. Do not force the gage into an undersized hole, as this can damage the tool steel surface and alter the calibrated diameter. Store in the protective case or sleeve provided to prevent nicks and dimensional changes.
