Vermont Gage 112412670 Class Zz Minus Plug Pin Gage

Product Description

The VERMONT GAGE 112412670 is a Class ZZ minus plug pin gage machined from steel and designed for NoGo inspection applications. It measures a nominal diameter of 12.67 mm with a tolerance of 0.00508 mm, making it suitable for verifying that a bore or hole does not exceed its maximum allowable size. At 2 inches in overall length and weighing 0.11 pounds, this compact gage is used by quality control technicians, machinists, and calibration professionals who require traceable, repeatable measurement results. Each unit ships with a Certificate of Accuracy backed by NIST traceability.

This plug pin gage is intended for use in dimensional inspection environments where NoGo gauging is required. Typical applications include checking bores in machined components, setting micrometers, and verifying verniers and other precision measuring devices. The Class ZZ designation indicates a commercial-grade tolerance class appropriate for general inspection use in production and quality lab settings. Its steel construction and 10 microfinish surface finish ensure consistent contact geometry across repeated measurements.

Compatibility

Designed for use as a NoGo plug gage in standard pin gage holders and inspection fixtures that accept 12.67 mm diameter gage pins. Also suitable for setting and verifying micrometers, verniers, and comparable precision measuring instruments.

Installation Notes

Plug pin gages are handled and used by quality control technicians and calibration professionals following standard metrology practices. Store the gage in a clean, dry environment away from contaminants that could affect surface finish or dimensional accuracy. Do not force the gage into a bore; apply only light, controlled pressure to avoid damage to the gage or workpiece. Periodic cleaning and inspection of the gage surface is recommended to maintain measurement integrity.
