Vermont Gage 112409230 Class Zz Minus Plug Pin Gage 9.23mm

Product Description

The VERMONT GAGE 112409230 is a Class ZZ Minus plug pin gage used for NoGo inspection of precision bored holes, machined features, and dimensional tolerances in manufacturing and quality control environments. The gage measures 9.23 mm in diameter with a tolerance of 0.00508 mm and an overall length of 2 inches. It is machined from steel with a 10 microfinish surface coating for consistent, repeatable contact. Each unit ships with a Certificate of Accuracy traceable to NIST standards, making it suitable for calibrated inspection processes. Dimensional inspection technicians, machinists, and quality assurance professionals are the primary users.

This pin gage is designed for NoGo inspection applications where confirming a feature does not exceed maximum material condition is required. It is also suited for setting and verifying micrometers, verniers, and other precision measuring devices. Typical use environments include machine shops, metrology labs, manufacturing production floors, and quality inspection stations handling close-tolerance components. The 9.23 mm diameter targets metric-dimensioned bores and features common in precision machined parts.

Installation Notes

Pin gages are handled and used by dimensional inspection technicians and machinists. Clean the gage and the feature being checked before use to prevent debris from affecting measurement accuracy. Do not force the gage into a bore - Class ZZ Minus gages are intended for NoGo inspection and should not enter a correctly sized hole. Store in the provided case or a clean, dry environment to protect the surface finish and dimensional integrity.
