Vermont Gage 112122260 Class Zz Plus Plug Gage 22.26mm

Product Description

The VERMONT GAGE 112122260 is a Class ZZ Plus plug gage designed for precision internal diameter inspection. It measures 22.26 mm in diameter with a tolerance of 0.00508 mm, making it suitable for go inspection tasks that demand close dimensional control. Manufactured from tool steel and finished to a 10 microfinish surface quality, this gage delivers the durability and accuracy required in production and quality-control environments. Each unit ships with a Certificate of Accuracy traceable to NIST, confirming it meets ASME B89.1 standards. Metrology technicians, quality inspectors, and machinists rely on this type of gage for verifying bores, holes, and fitted components.

This plug gage is used in manufacturing, machine shops, and inspection labs where go-type internal diameter verification is required. It is appropriate for use alongside set micrometers, verniers, and other precision measuring devices. The 22.26 mm diameter targets applications where metric bore tolerances must be validated before parts advance through production. Its compact overall length of 2.0000 inches allows use in benchtop and in-line inspection setups.

Compatibility

Designed as an OEM-style go plug gage for use with set micrometers, verniers, and other calibrated measuring devices requiring a 22.26 mm diameter reference standard.

Installation Notes

Plug gages of this type are handled and used by quality technicians and metrology personnel, not installed in mechanical systems. Store the gage in its protective case when not in use to prevent surface damage or corrosion. Clean the gage and the workpiece bore before inspection to ensure accurate readings. Do not force the gage into an undersized bore, as this will damage the gage surface and compromise measurement integrity.
