Vermont Gage 911228200 Class Zz Minus Plug Pin Gage 0.2820 in

Product Description

The VERMONT GAGE 911228200 is a Class ZZ Minus plug pin gage designed for NoGo inspection work in dimensional measurement applications. The gage measures 0.2820 inches in diameter with a tolerance of 0.0002 inches, making it suitable for verifying that a hole or bore does not fall below minimum acceptable dimensions. Constructed from steel with a black oxide finish, it measures 2 inches in overall length. Each unit ships with a Certificate of Accuracy traceable to NIST standards, confirming calibration integrity for quality-controlled environments.

This plug pin gage is used in manufacturing inspection, machining, and quality control settings where NoGo gauging is required. It is also appropriate for setting and verifying micrometers, verniers, and other precision measuring devices. The 0.2820-inch diameter makes it a direct-use gage for inspection of corresponding bored, drilled, or reamed features. Machinists, quality technicians, and metrology professionals working in both job-shop and production environments will find this gage suited to their go/no-go inspection workflows.

Installation Notes

Plug pin gages are handled and used by quality control technicians and machinists. Keep the gage clean and lightly oiled when not in use to prevent corrosion. Do not force the gage into a feature being inspected, as this can damage the gage or the workpiece. Store in a protective case away from temperature extremes to maintain dimensional stability and calibration integrity.
