Vermont Gage 112302830 Class Zz Plus Plug Gage 2.83 Mm

Product Description

The VERMONT GAGE 112302830 is a Class ZZ Plus plug gage designed for precision dimensional inspection of small-diameter bores and holes. It measures 2.83 mm in diameter and carries a tolerance of 0.00508 mm, making it suitable for Go inspection applications where tight dimensional verification is required. Manufactured from tool steel with a 10 microfinish coating, it delivers consistent, repeatable measurements. Each unit ships with a Certificate of Accuracy traceable to NIST, meeting ASME B89.1 standards. Machinists, quality technicians, and metrology professionals use this gage to verify hole diameters during production and incoming inspection processes.

This plug gage is used in machine shops, manufacturing facilities, and quality control labs where small-bore dimensional verification is part of standard workflow. It is suited for Go inspection routines and can be used alongside micrometers, verniers, and other precision measuring devices to validate bore conformance. Its compact size and precise tolerance make it practical for high-volume inspection of machined components where accuracy at the sub-millimeter level is critical.

Key Features

Compatibility

Designed for use in Go inspection applications and compatible with standard plug gage handles. Suitable for use alongside micrometers, verniers, and other precision measuring devices in dimensional inspection setups.

Installation Notes

Plug gages should be handled and stored by qualified quality or metrology personnel to prevent damage to the precision-ground surface. Clean the gage and bore thoroughly before use to avoid measurement errors caused by debris or contamination. Do not force the gage into a bore; smooth, controlled insertion is required to protect the tool steel surface and preserve accuracy. Store in a protective case away from temperature extremes to maintain dimensional integrity.
