Vermont Gage 112122460 Class Zz Plus Plug Gage 22.46 Mm

Product Description

The VERMONT GAGE 112122460 is a Class ZZ Plus plug gage designed for go inspection of bored, reamed, and drilled holes at a nominal diameter of 22.46 mm. Manufactured from tool steel with a 10 microfinish surface coating, this gage delivers a tolerance of 0.005 mm, making it well-suited for verifying hole dimensions on the production floor or in the inspection room. Each unit ships with a Certificate of Accuracy that includes NIST traceability, confirming the gage meets ASME B89.1 standards. Machinists, quality technicians, and metrology professionals install and use this gage as part of go/no-go inspection routines or to set micrometers, verniers, and other measuring devices.

This plug gage is appropriate for use in machine shops, manufacturing facilities, and quality control environments where precise hole-size verification is required. It is sized for go inspection at 22.46 mm and is compatible with standard gage handle systems. The 10 microfinish surface reduces wear and ensures consistent, repeatable contact with the bore being checked. Its compact overall length of 2.0000 inches makes it easy to handle in bench or inline inspection setups.

Installation Notes

Plug gages are installed and used by quality technicians and machinists following standard metrology practices. Before use, clean the gage and bore thoroughly to remove chips, coolant, and debris that could affect measurement accuracy. Handle the gage carefully to avoid dropping or striking it against hard surfaces, as impact damage can alter the gage dimension and void traceability. Store in a protective case away from temperature extremes to maintain dimensional stability.
