Vermont Gage 112411250 Class Zz Minus Plug Pin Gage 11.25mm

Product Description

The VERMONT GAGE 112411250 is a Class ZZ minus plug pin gage ground to a nominal diameter of 11.25 mm with a tolerance of 0.00508 mm. It is manufactured from steel with a 10 microfinish surface coating for consistent, repeatable measurement contact. This gage is used to perform NoGo attribute inspection on bored, reamed, or machined holes, confirming that a feature has not been cut oversize. Each unit ships with a Certificate of Accuracy traceable to NIST, meeting quality system documentation requirements for incoming inspection, production floor verification, and calibration recordkeeping. Machinists, quality technicians, and metrology lab personnel are the primary users.

This pin gage is sized for inspection tasks requiring precise go/no-go verification of 11.25 mm diameter features. Typical applications include setting and checking micrometers, verniers, and other measuring devices, as well as direct hole inspection in manufacturing and machine shop environments. The minus designation indicates the gage is ground below nominal, making it suitable for the NoGo member of a gage pair. Overall length is 2 inches, keeping the tool compact for use in confined feature locations.

Compatibility

Designed for NoGo hole inspection and for setting micrometers, verniers, and other measuring devices requiring an 11.25 mm Class ZZ minus reference standard.

Installation Notes

Pin gages are handled and used by quality technicians and machinists; no installation in a mechanical system is required. Always clean the gage and the feature under inspection before use to prevent false readings caused by debris or coolant residue. Store the gage in its protective case and avoid contact with other metal tools to preserve the ground surface finish. Do not force the gage into a feature; apply only light, consistent hand pressure to avoid gage or workpiece damage.
