Vermont Gage 112119120 Class Zz Plus Plug Gage 19.12mm

Product Description

The VERMONT GAGE 112119120 is a Class ZZ Plus plug gage manufactured from tool steel for dimensional inspection work. It measures a nominal diameter of 19.12 mm with a tolerance of 0.00508 mm, making it suitable for go inspection applications where close-tolerance bore verification is required. The gage has an overall length of 2.0000 inches and weighs 0.26 pounds. Each unit ships with a Certificate of Accuracy backed by NIST traceability. It is designed for use by quality control technicians, machinists, and metrology professionals who need a reliable, standards-conforming plug gage for production or inspection environments.

This plug gage is used in machine shops, manufacturing facilities, and inspection labs for verifying bore diameters on machined components. Class ZZ Plus gages are appropriate for go inspection checks and for setting and verifying micrometers, verniers, and other precision measuring devices. The 19.12 mm diameter makes it a practical reference standard for metric bore tolerancing applications in both light production and quality assurance settings. The included NIST-traceable certificate supports compliance documentation requirements common in ISO and aerospace inspection workflows.

• Suitable for setting micrometers, verniers, and other measuring devices

Compatibility

Designed for go inspection of 19.12 mm nominal diameter bores and for use as a reference standard with micrometers, verniers, and other calibrated measuring devices in conformance with ASME B89.1.

Installation Notes

Plug gages should be handled by qualified metrology or quality control personnel. Clean the gage and the bore being inspected before use to prevent debris from affecting measurement accuracy. Store the gage in its protective case away from temperature extremes to maintain dimensional integrity. Do not force the gage into an undersized bore, as this can damage both the gage and the workpiece.
