Vermont Gage 112306190 Class Zz Plus Plug Gage 6.19mm

Product Description

The VERMONT GAGE 112306190 is a Class ZZ Plus cylindrical plug gage machined from tool steel for use in precision dimensional inspection. It measures 6.19 mm in diameter with a tolerance of 0.00508 mm and a 10 microfinish surface finish, making it suitable for tight-tolerance go inspection work. The gage ships with a Certificate of Accuracy traceable to NIST, confirming it meets ASME B89.1 standards. At 2.0000 inches overall length, it fits standard gage handle sets and integrates easily into a shop inspection workflow. Machinists, quality technicians, and metrology personnel rely on this type of gage for fast, reliable bore and hole verification on the production floor or in the inspection lab.

This plug gage is used for go inspection of bored, reamed, or drilled holes at the 6.19 mm nominal diameter. It is also suited for setting and verifying micrometers, verniers, and other measuring devices that require a traceable dimensional reference. Typical applications include incoming inspection, in-process quality checks, and final acceptance testing in manufacturing environments. The NIST-traceable Certificate of Accuracy supports documentation requirements in ISO 9001 and AS9100 quality systems.

Key Features

• 2.0000 inches overall length compatible with standard gage handle sets

Compatibility

Designed as a go plug gage for use with standard gage handle sets and applicable to bore and hole inspection at 6.19 mm nominal diameter. Also suitable for setting micrometers, verniers, and other calibrated measuring devices per the manufacturer application data.

Installation Notes

Plug gages of this type are handled and used by quality technicians and machinists following standard metrology practices. Insert the gage into the bore with light, controlled hand pressure only - never force a plug gage, as this can damage the gage or the workpiece. Keep the gage clean and lightly oiled when stored to prevent corrosion on the tool steel surface. Reference ASME B89.1 and your facility quality procedures for proper gage handling, calibration intervals, and storage requirements.
