Vermont Gage 111263100 Class Zz Minus Plug Pin Gage 0.6310 in

Product Description

The VERMONT GAGE 111263100 is a Class ZZ Minus plug pin gage designed for NoGo inspection work in precision measurement applications. Machined from steel, this pin gage measures 0.6310 inches in diameter with an overall length of 2 inches and holds a tolerance of 0.0002 inches. Each unit ships with a Certificate of Accuracy backed by NIST traceability, confirming the gage meets Class ZZ dimensional standards. It is the appropriate tool when a machinist or quality technician needs to verify that a bore or hole does not exceed its maximum allowable size. The Minus designation indicates the gage is ground to the lower end of the tolerance band.

This pin gage is used in quality control and inspection environments across manufacturing, tooling, and machine shops. It is suited for NoGo bore checks and for setting and verifying micrometers, verniers, and other measuring devices. The gage is appropriate for any application that requires a traceable, repeatable reference standard at the 0.6310-inch diameter. Both professional metrologists and skilled machinists working in production inspection use this type of gage as part of a standard go/no-go inspection routine.

Compatibility

Designed as an OEM-style Class ZZ plug pin gage for use in NoGo bore inspection routines and as a reference standard for setting micrometers, verniers, and comparable precision measuring instruments.

Installation Notes

Pin gages should be handled with clean, dry hands or lint-free gloves to prevent corrosion from skin oils. Store the gage in its case or a protected environment when not in use to maintain surface integrity and dimensional accuracy. Verify the gage against a known traceable standard at regular calibration intervals per your facility quality plan. No mechanical installation is required; the gage is a hand-held inspection tool used by quality technicians and machinists.
