Vermont Gage 112206220 Class Zz Plug Pin Gage 6.22mm

Product Description

The VERMONT GAGE 112206220 is a Class ZZ minus plug pin gage designed for precision dimensional inspection in metrology and quality control applications. Machined from steel with a 10 microfinish surface coating, this pin gage measures 6.22 mm in diameter with a tolerance of 0.00508 mm. The overall length is 2 inches. It is supplied with a Certificate of Accuracy traceable to NIST, making it suitable for documented inspection programs. Machinists, quality technicians, and tool room personnel use pin gages like this one to verify bore diameters and check tooling calibration quickly and reliably.

This gage is configured for NoGo inspection use, meaning it validates that a hole or bore does not exceed the maximum allowable size for a given tolerance. It is appropriate for use with go/nogo gage sets, setting micrometers, verniers, and other precision measuring devices. Applications span manufacturing floor inspection, incoming quality control, and tool calibration in job shops, production facilities, and metrology labs. The minus classification indicates the pin is ground to the lower boundary of the Class ZZ tolerance band, which is standard for NoGo members in a gage set.

Key Features

• Class ZZ minus tolerance ground to 0.00508 mm for NoGo inspection applications
• 6.22 mm measurement diameter with steel construction and 10 microfinish surface coating
• NIST-traceable Certificate of Accuracy included for documented quality programs
• 2-inch overall length suits standard pin gage handles and collet-style holders
• Configured for use with micrometers, verniers, and other precision measuring devices

Compatibility

Designed for NoGo inspection use with standard pin gage handles, setting micrometers, verniers, and other precision measuring devices as noted in the product specifications.

Installation Notes

Pin gages are handled and used by quality technicians and machinists following standard metrology practices. Clean and inspect the gage and the bore or measuring device before use to prevent contamination that could affect readings. Do not force the pin into a bore; light hand pressure is the correct technique for a properly sized NoGo check. Store in the original case or a protected holder to preserve the ground finish and dimensional integrity.
