Vermont Gage 112308230 Class Zz Plus Plug Gage 8.23 Mm

Product Description

The VERMONT GAGE 112308230 is a Class ZZ Plus plug gage machined from tool steel for dimensional go inspection of hole diameters. It measures 8.23 mm in diameter with a tolerance of 0.005 mm (0.00508 mm), making it suitable for verifying bore dimensions to tight tolerances in production or inspection environments. The overall length is 2.0 inches. A Certificate of Accuracy with NIST traceability is included, supporting quality documentation requirements. This gage is used by machinists, quality technicians, and metrology professionals who need reliable, repeatable dimensional verification.

This plug gage is suited for go inspection of 8.23 mm diameter holes in manufacturing, toolroom, and quality control settings. It is compatible with standard gage handle sets and is also used to set and verify micrometers, verniers, and other measuring devices. The Class ZZ Plus tolerance class is appropriate for general-purpose inspection where moderate precision is required. Both production floor and lab environments are common deployment scenarios.

Key Features

Compatibility

Designed for use with standard plug gage handles for go inspection of 8.23 mm diameter bores. Also suitable for setting micrometers, verniers, and other measuring devices requiring a certified reference diameter.

Installation Notes

Plug gages are handled and used by quality technicians and machinists - no power tools or fasteners are required. Store the gage in its protective case when not in use to prevent damage to the precision-ground surface. Clean bore and gage surfaces before use to avoid false readings. Do not force the gage into an undersized hole, as this can damage both the gage and the workpiece.
