Vermont Gage 112405330 Class Zz Minus Plug Pin Gage 5.33mm

Product Description

The VERMONT GAGE 112405330 is a Class ZZ Minus plug pin gage machined from steel for precise NoGo inspection of bored holes, machined features, and other critical dimensional checkpoints. It measures 5.33 mm in diameter and holds a tolerance of 0.00508 mm, meeting the requirements of Class ZZ minus-tolerance gaging standards. Each unit ships with a Certificate of Accuracy traceable to NIST, providing documented traceability for quality systems and calibration records. The 10 microfinish surface coating reduces wear during repeated insertions and helps maintain dimensional integrity over the service life of the gage. Machinists, quality technicians, and inspection personnel use this gage in production and calibration environments.

This plug pin gage is suited for NoGo inspection applications in machine shops, manufacturing facilities, and metrology labs. It is used to verify that a bored or reamed hole does not exceed its maximum allowable size, confirming the hole remains within specified tolerance. The gage also serves as a reference standard when setting micrometers, verniers, and other measuring devices to a known dimension. At 2 inches in overall length, it fits standard pin gage handles and can be used freehand for quick go or nogo checks on production floors or inspection benches.

Compatibility

Designed for NoGo inspection use and as a setting reference for micrometers, verniers, and other measuring devices. Compatible with standard pin gage handles that accept 5.33 mm diameter pin gages.

Installation Notes

This gage should be handled by qualified inspection or metrology personnel familiar with Class ZZ gaging practices. Before use, clean the gage and the feature being inspected to remove debris, oil, or coolant that could affect the measurement. Do not force the gage into a hole; apply light, consistent hand pressure only. Store in a protective case away from temperature extremes to preserve dimensional stability and surface finish.
