Vermont Gage 112403170 Class Zz Plug Pin Gage 3.17mm

Product Description

The VERMONT GAGE 112403170 is a Class ZZ minus plug pin gage designed for precise dimensional inspection in quality control and metrology applications. With a measurement diameter of 3.17 mm and a tolerance of 0.00508 mm, this pin gage delivers the accuracy required for NoGo inspection work. The steel construction and 10 microfinish surface coating ensure consistent, reliable contact during measurement. Each unit ships with a Certificate of Accuracy backed by NIST traceability, making it suitable for use in calibrated inspection environments. Licensed metrology technicians and quality control professionals are the primary users of this tool.

This pin gage is used in dimensional inspection setups where a NoGo gage member is required to verify that a feature does not exceed its maximum material condition. It is also compatible with set micrometers, verniers, and other precision measuring devices as a calibration or setup reference. The 2-inch overall length provides adequate clearance for most bench-top inspection fixtures. Suitable for light manufacturing, machining shops, and quality labs handling small-bore or close-tolerance work.

Compatibility

Designed for use in NoGo inspection applications and as a reference standard for set micrometers, verniers, and other precision measuring devices requiring a 3.17 mm diameter pin gage.

Installation Notes

Pin gages should be handled by qualified metrology or quality control personnel following established inspection procedures. Keep the gage clean and lightly oiled when stored to prevent corrosion on the steel surface. Never force a plug gage into a bore; apply only hand pressure during inspection to avoid damage to the gage or the workpiece. Store in the provided case or a protective sleeve to preserve the 10 microfinish surface finish.
