Vermont Gage 112119320 Class Zz Plus Plug Gage 19.32mm

Product Description

The VERMONT GAGE 112119320 is a Class ZZ Plus plug gage designed for dimensional inspection of machined bores and holes. It measures 19.32 mm in diameter with a tolerance of 0.00508 mm (0.005 mm), providing the precision required for go-inspection applications and calibration workflows. Constructed from tool steel with a 10 micro-inch surface finish, this plug gage delivers consistent, repeatable results in production and quality control environments. Each unit ships with a Certificate of Accuracy traceable to NIST, meeting ASME B89.1 dimensional measurement standards. Machinists, quality technicians, and metrology lab personnel rely on this type of gage for reliable bore verification.

This plug gage is suited for go inspection tasks on bored, drilled, or reamed features in both production floor and metrology lab settings. It is also used to set and verify micrometers, verniers, and other measuring devices where a precision reference is needed. The 2.0000-inch overall length provides a comfortable handle reach for single-hand operation during inline or bench inspection. Typical users include quality control inspectors in manufacturing, tool and die shops, and precision machining facilities working to close-tolerance print requirements.

Compatibility

Designed for go inspection of machined bores and holes at 19.32 mm nominal diameter, and for use as a reference setting standard with micrometers, verniers, and comparable measuring instruments.

Installation Notes

Plug gages are used by quality technicians and machinists and require no permanent installation. Before use, clean the gage and the workpiece bore thoroughly to remove chips, oil, and debris that could affect measurement accuracy. Handle the gage by the knurled handle or body to avoid thermal expansion from hand heat affecting readings. Store in a protective case away from abrasive materials to preserve the precision-ground surface finish.
