Vermont Gage 112304670 Class Zz Plus Plug Gage 4.67 Mm

Product Description

The VERMONT GAGE 112304670 is a Class ZZ Plus plug gage designed for precision bore and hole inspection in manufacturing and metrology applications. Built from tool steel with a 10 microfinish surface, this gage measures a nominal diameter of 4.67 mm with a tolerance of 0.00508 mm, meeting the requirements of ASME B89.1. It is used during go inspection routines to verify that a hole or bore falls within the acceptable dimensional range. Machinists, quality control technicians, and calibration professionals rely on this type of gage for fast, reliable attribute inspection at the workbench or inspection station. Each unit ships with a Certificate of Accuracy with NIST traceability.

This plug gage is suited for go inspection of 4.67 mm diameter features in both production and quality lab environments. It works alongside micrometers, verniers, and other measuring devices as part of a complete dimensional verification process. The overall length of 2.0000 inches allows comfortable handling in standard gage holders. It is appropriate for light manufacturing, precision machining shops, and inspection departments requiring certified dimensional tooling.

Key Features

Compatibility

Designed for use with standard plug gage handles and compatible with go inspection routines alongside micrometers, verniers, and other precision measuring devices per ASME B89.1.

Installation Notes

Plug gages should be handled by calibration technicians or quality inspection personnel familiar with ASME dimensional standards. Keep the gage clean and lightly oiled when not in use to prevent corrosion on the tool steel surface. Do not force the gage through a bore; excessive force will cause premature wear and compromise measurement accuracy. Store in a protective case away from temperature extremes to maintain calibration integrity.
