Vermont Gage 111269100 Class Zz Minus Plug Pin Gage 0.6910 in

Product Description

The VERMONT GAGE 111269100 is a Class ZZ Minus plug pin gage with a 0.6910-inch measurement diameter, designed for NoGo inspection applications in precision machining and quality control environments. Machined from steel with a 10 micro surface finish, this pin gage delivers a tolerance of 0.0002 inches and ships with a Certificate of Accuracy backed by NIST traceability. Overall length is 2 inches. Calibration technicians, machinists, and quality inspectors use this gage to verify that bored holes, drilled passages, and machined features do not exceed the maximum allowable tolerance limit.

This pin gage is suited for NoGo go-no-go inspection routines on the shop floor or in a metrology lab. It is also used to set and verify micrometers, verniers, and other hand measuring devices that require a certified reference standard. The Class ZZ designation indicates a commercial-grade tolerance class appropriate for general inspection work rather than master-gage or reference-gage applications. It fits naturally into standard gage-pin sets and works alongside go-pin counterparts to provide complete tolerance verification at the 0.6910-inch nominal size.

Key Features

• 0.6910-inch measurement diameter with 0.0002-inch tolerance for precise NoGo inspection
• Class ZZ Minus designation — commercial-grade tolerance class for general quality-control use
• Steel construction with 10 micro surface finish for dimensional stability and wear resistance
• 2-inch overall length provides comfortable handling and consistent insertion depth
• Includes Certificate of Accuracy with NIST traceability for documented calibration compliance
• Suitable for setting micrometers, verniers, and other measuring devices to a certified reference

Compatibility

Designed for use in standard plug gage and go-no-go inspection setups requiring a 0.6910-inch NoGo pin reference; also compatible with micrometer and vernier setting applications at that nominal diameter.

Installation Notes

Plug pin gages are handled and used by calibration technicians, quality inspectors, and machinists — no power tools or utility shutoffs are required. Handle the gage with clean, dry hands or inspection gloves to prevent corrosion from skin oils, and store in a protective case when not in use. Do not force the pin into a feature; NoGo pins should not enter a conforming hole under normal hand pressure. Periodic recalibration against a NIST-traceable standard is recommended to maintain accuracy over time.
