Vermont Gage 111272000 Class Zz Minus Plug Pin Gage 0.72 in

Product Description

The VERMONT GAGE 111272000 is a Class ZZ Minus plug pin gage machined from steel and used to perform NoGo inspection checks on precision bores, holes, and machined features. At 0.7200 inches in diameter and 2 inches in overall length, this single-end pin gage is designed for use in quality control, calibration labs, and production floor inspection environments. Each gage ships with a Certificate of Accuracy with NIST Traceability, confirming the dimensional tolerance of 0.0002 inches. Machinists, quality technicians, and metrology professionals use this type of gage to verify that a feature does not exceed its maximum allowable size, which is the core function of a NoGo gage in a go/no-go inspection routine.

This gage is suited for dimensional inspection tasks in manufacturing, toolroom, and quality assurance settings. Typical applications include checking bored holes, reamed features, and toleranced openings against drawing specifications. The 0.7200-inch minus-class designation makes it appropriate for use alongside setting micrometers, verniers, and other precision measuring devices when confirming hole acceptance criteria. It is a standard bench tool in environments where part conformance to tight tolerances must be documented and traceable to a national standard.

Key Features

• Class ZZ Minus tolerance designation for NoGo inspection use
• 0.7200 inch measurement diameter with 0.0002 inch tolerance
• 2 inch overall length for easy handling on the bench or floor
• Steel construction for durability and dimensional stability

• Includes Certificate of Accuracy with NIST Traceability

Compatibility

Designed for use in NoGo inspection routines and for setting or verifying micrometers, verniers, and other precision measuring devices requiring a 0.7200 inch reference diameter.

Installation Notes

Pin gages are handled and used by quality technicians and machinists and require no permanent installation. Store the gage in its protective case when not in use to prevent nicks, corrosion, or dimensional damage. Clean contact surfaces before use and never force the gage into a feature, as forcing can damage both the gage and the workpiece. Handle with clean cotton or nitrile gloves to prevent oils from affecting accuracy or promoting surface corrosion on the steel body.
