Vermont Gage 111153300 Class Zz Plus Plug Gage 0.533 in

Product Description

The VERMONT GAGE 111153300 is a Class ZZ Plus plug gage machined from tool steel and designed for precision dimensional inspection of cylindrical bores and holes. Measuring 0.533 inches in diameter with a tolerance of 0.0002 inches, this gage delivers the accuracy required for Go inspection routines on the shop floor or in the metrology lab. The 10 microinch surface finish on the gaging element ensures consistent contact with the workpiece. Each unit ships with a Certificate of Accuracy traceable to NIST, meeting ASME B89.1 standards. Machinists, quality technicians, and toolroom inspectors use this gage as a direct, reliable check for in-tolerance bore dimensions.

This plug gage is suited for Go inspection applications in manufacturing and quality control environments. It is commonly used alongside set micrometers, verniers, and other measuring devices to verify bore acceptance. The 0.533-inch diameter makes it appropriate for close-tolerance work in general machining, tooling, and precision fabrication. At 2.0 inches overall length, the gage handles easily in standard single-end or double-end gage handle setups used in production and inspection departments.

Compatibility

Designed for use in Go inspection routines and compatible with set micrometers, verniers, and other measuring devices as stated by the manufacturer. Fits standard plug gage handles sized for 0.533-inch gage blanks.

Installation Notes

Plug gages are handled and used by quality technicians and machinists — no permanent installation is required. Store the gage in its protective case when not in use to prevent surface damage to the gaging element. Clean the bore and gage surfaces before use to avoid false readings caused by chips or debris. Do not force the gage into an undersized bore, as this can damage the precision-ground surface finish and affect calibration.
