Vermont Gage 112122240 Class Zz Plus Plug Gage 22.24 Mm

Product Description

The VERMONT GAGE 112122240 is a Class ZZ Plus plug gage used to verify bore diameters during go inspection of machined parts. Manufactured from tool steel, this gage is ground and lapped to a 10 microfinish with a tolerance of 0.00508 mm, ensuring precise conformance to ASME B89.1 dimensional standards. Each unit ships with a Certificate of Accuracy traceable to NIST, which is a requirement in most quality-controlled manufacturing and metrology environments. The overall length is 2.0000 inches, and the gage weighs 0.35 pounds. Machinists, quality technicians, and metrology lab personnel use this tool as a direct go-check reference for 22.24 mm diameter bores.

This plug gage is suited for use in precision manufacturing inspection, tool room measurement, and calibration lab environments. It is compatible with standard gage handle systems and is used alongside set micrometers, verniers, and other measuring devices when qualifying machined components to tight bore tolerances. Applications include production floor go inspection for small-run and high-volume machining operations in aerospace, automotive, and general manufacturing settings.

Compatibility

Designed for use as a go inspection gage for 22.24 mm diameter bores. Compatible with set micrometers, verniers, and other standard measuring devices per the ASME B89.1 standard. Fits standard plug gage handle systems sized for this diameter range.

Installation Notes

Plug gages are installed and used by quality technicians and machinists in inspection settings. Before use, clean the bore and gage surfaces thoroughly to remove chips, coolant, and debris that could affect measurement accuracy. Handle with care to avoid dropping or contact with hard surfaces, as any impact may alter the precision ground surface. Store in the included case or a clean, dry environment to prevent corrosion of the tool steel body.
