Vermont Gage 112208680 Class Zz Minus Plug Pin Gage 8.68mm

Product Description

The VERMONT GAGE 112208680 is a Class ZZ Minus plug pin gage machined to a 8.68 mm diameter with a tolerance of 0.00508 mm. It is used to verify that a hole or bore does not exceed its maximum allowable size, making it a NoGo inspection tool. The gage is manufactured from steel and features a 10 microfinish surface coating for consistent contact and accurate readings. Each unit ships with a Certificate of Accuracy traceable to NIST standards. At 2 inches in overall length and 0.06 pounds, it is compact and suited for bench or field inspection work performed by machinists, quality control technicians, and precision measurement professionals.

This gage is applied in dimensional inspection of machined bores, drilled holes, and precision-fit components where hole size must be held within tight tolerances. It is commonly used alongside micrometers, verniers, and other measuring devices during incoming inspection, in-process quality checks, and final acceptance procedures. The Class ZZ designation indicates a commercial-grade tolerance class appropriate for general inspection use. Its NoGo function confirms that a feature does not exceed the upper limit of its tolerance band.

Installation Notes

Plug pin gages should be handled with clean, dry hands or cotton gloves to prevent corrosion from skin oils. Before use, inspect the gage surface for burrs or damage that could affect measurement accuracy. Store in a protective case away from other metal tools to preserve the finished surface. Calibration intervals should follow your facility quality system requirements and any applicable ISO or ANSI inspection standards.
