Vermont Gage 112212660 Class Zz Minus Plug Pin Gage 12.66mm

Product Description

The VERMONT GAGE 112212660 is a Class ZZ Minus plug pin gage designed for precision dimensional inspection in machining and manufacturing environments. This single-end pin gage measures a nominal diameter of 12.66 mm with a tolerance of 0.00508 mm, making it suitable for NoGo inspection applications where tight dimensional control is required. Manufactured from steel with a 10 microfinish surface coating, it provides consistent, repeatable results. Each gage ships with a Certificate of Accuracy that includes NIST traceability, confirming it meets established metrology standards. Machinists, quality control technicians, and tool-room inspectors rely on this type of gage for verifying bore and hole dimensions during production and final inspection.

This pin gage is used in NoGo inspection routines to confirm that a bore or hole does not exceed the maximum allowable diameter. It is also well suited for setting and verifying micrometers, verniers, and other measuring devices in shop or lab environments. Applicable in both production floor and quality lab settings, this gage fits standard gage block and handle systems used in general precision inspection work. Its compact 2-inch overall length makes it easy to handle in tight inspection setups. The Class ZZ designation indicates it meets industry tolerance standards for general-purpose inspection gages.

Installation Notes

Pin gages should be handled with clean, dry hands or lint-free gloves to prevent contamination of the precision ground surface. Store the gage in its protective case when not in use to avoid surface damage. Before use, verify the gage surface is free of burrs, debris, or corrosion that could affect measurement accuracy. Inspection procedures using precision gages should follow applicable shop standards and calibration intervals as defined by your quality management system.
