Vermont Gage 111268800 Class Zz Minus Plug Gage 0.6880 in

Product Description

The VERMONT GAGE 111268800 is a Class ZZ Minus plug pin gage used to inspect hole diameters and verify dimensional tolerances in machined parts. With a measurement diameter of 0.6880 inches and a tolerance of 0.0002 inches, this pin gage delivers the precision required for NoGo inspection applications. At 2 inches overall length, it fits standard pin gage handles and works alongside micrometers, verniers, and other measuring devices. It ships with a Certificate of Accuracy traceable to NIST standards. Machined from steel with a 10 micro finish, this gage is suited for quality control environments, tool rooms, and production floor inspection stations.

This Class ZZ Minus pin gage is used in NoGo inspection routines to confirm that a feature does not fall outside its maximum material condition. It is well-suited for dimensional inspection of bores and holes in machined components across manufacturing, fabrication, and tooling operations. The gage can also be used to set and verify micrometers, verniers, and similar precision measuring instruments. Machinists, quality control technicians, and metrologists working in both job-shop and production environments will find this gage appropriate for repeatable go/no-go inspection workflows.

Compatibility

Designed for use in NoGo inspection applications and for setting micrometers, verniers, and other precision measuring devices requiring a 0.6880 inch reference diameter.

Installation Notes

Pin gages should be handled with clean, dry hands or cotton gloves to prevent corrosion from skin oils. Store in a protective case away from other metal tooling to avoid surface damage. When inserting the gage into a bore, apply only light, consistent hand pressure — never force the gage. Calibration intervals should follow your facility's quality management system requirements to maintain NIST-traceable accuracy.
