Vermont Gage 111174800 Class Zz Plus Plug Gage 0.748 in

Product Description

The VERMONT GAGE 111174800 is a Class ZZ Plus plug gage used to verify bore and hole diameters in precision machining and quality control environments. Measuring 0.748 inches in diameter, it holds a tolerance of 0.0002 inches and carries a 10 microinch surface finish. Made from tool steel, this gage delivers the dimensional consistency required for go inspection operations. It ships with a Certificate of Accuracy backed by NIST traceability, meeting ASME B89.1 standards. Machinists, toolroom technicians, and quality control inspectors use this type of gage in production settings where tight dimensional verification is required.

This plug gage is suited for go inspection of bored, drilled, or reamed holes in both production and toolroom settings. It is also used to set and verify micrometers, verniers, and other measuring devices requiring a known reference diameter. The 0.748 inch size fits common inspection needs in general machining and precision manufacturing. At 2.0 inches overall length, the gage provides adequate handling clearance for standard bench and floor inspection use. Residential and light commercial applications are not typical — this is a precision metrology tool intended for industrial and manufacturing environments.

Key Features

Compatibility

Designed for go inspection of holes and bores at 0.748 inches nominal diameter, and for use as a reference setting standard with micrometers, verniers, and other precision measuring devices.

Installation Notes

Plug gages are handled and used by trained machinists or quality control technicians — no power source or utility shutoff is required. Store the gage in its protective case and avoid contact with abrasive surfaces to preserve the microfinish. Clean the gage and the workpiece bore before use to prevent debris from affecting readings or causing surface damage. Calibration intervals should follow your facility quality management program in accordance with ASME B89.1 guidelines.
