Vermont Gage 112211100 Class Zz Minus Plug Pin Gage 11.10 Mm

Product Description

The VERMONT GAGE 112211100 is a Class ZZ Minus plug pin gage used to perform NoGo dimensional inspection on bored, drilled, or reamed holes. Manufactured from steel with a 10 microfinish surface coating, this pin gage measures a nominal diameter of 11.10 mm and carries a tolerance of 0.00508 mm. At 2 inches overall length, it fits standard pin gage handles and fits comfortably into precision measurement workflows. Each unit ships with a Certificate of Accuracy traceable to NIST, making it suitable for quality control programs that require documented traceability. Machinists, quality technicians, and tool room personnel rely on this type of gage for fast, reliable pass/fail hole verification.

This pin gage is intended for NoGo inspection applications where hole diameter must be confirmed to fall within a specified tolerance band. It is also used to set and verify micrometers, verniers, and other measuring devices requiring a known reference diameter. Typical environments include machine shops, production floors, and inspection labs working with close-tolerance machined components. The Class ZZ designation indicates a commercial-grade tolerance class appropriate for general inspection use rather than master or working-standard applications.

Compatibility

Designed for use with standard pin gage handle sets and compatible with micrometers, verniers, and other measuring devices requiring a calibrated reference pin for NoGo inspection at 11.10 mm nominal diameter.

Installation Notes

Pin gages should be handled with clean, dry hands or lint-free gloves to prevent corrosion from skin oils. Insert the pin gage into the workpiece hole with light, even hand pressure - do not force the pin, as forcing can damage both the gage and the part. Store in a protective case away from other tooling to prevent surface damage to the precision finish. Periodic cleaning and inspection for wear or scoring is recommended to maintain measurement accuracy.
