Vermont Gage 112415290 Class Zz Minus Plug Pin Gage 15.29mm

Product Description

The VERMONT GAGE 112415290 is a Class ZZ Minus plug pin gage machined from steel and used to verify bore and hole dimensions in precision inspection work. At 15.29 mm diameter with a tolerance of 0.00508 mm, this gage is purpose-built for NoGo inspection - confirming that a feature does not exceed its maximum material condition. The overall length is 2 inches, and the 10 micro coating finish protects the gage surface and helps maintain dimensional integrity over repeated use. Each unit ships with a Certificate of Accuracy traceable to NIST standards, making it suitable for quality-controlled environments and audit documentation.

This plug pin gage is used in manufacturing, metrology labs, and quality control settings where tight-tolerance bore verification is required. It works alongside set micrometers, verniers, and other precision measuring devices as part of a go/nogo inspection routine. The Class ZZ designation places it in the standard commercial-grade tolerance range, appropriate for general inspection of machined components in mechanical and industrial applications. Licensed metrology technicians and quality inspectors are the primary users.

Compatibility

Designed for use in NoGo inspection applications alongside set micrometers, verniers, and other precision measuring devices where 15.29 mm bore verification is required.

Installation Notes

Pin gages are handled and used by quality control technicians and metrologists following standard inspection procedures. Clean the gage and the workpiece bore before use to prevent debris from affecting measurement accuracy. Do not force the gage into a bore - light hand pressure is the correct technique for Class ZZ plug gages. Store in a protective case away from temperature extremes to preserve dimensional stability.
