Vermont Gage 111120500 Class Zz Plus Plug Gage 0.205 in

Product Description

The VERMONT GAGE 111120500 is a Class ZZ Plus plug gage machined from tool steel for precision go inspection of bored, drilled, and reamed holes. The gage measures 0.205 inches in diameter with a tolerance of 0.0002 inches and a 10 microfinish surface finish on the gage member. At 2.0 inches overall length, it fits easily in hand for bench or in-process inspection. Every unit ships with a Certificate of Accuracy traceable to NIST, meeting ASME B89.1 requirements. Machinists, toolroom technicians, and quality inspectors rely on this type of gage for fast, repeatable attribute verification of hole size.

This plug gage is intended for go inspection of holes at the 0.205-inch nominal diameter. It is also suited for setting and checking the calibration of micrometers, verniers, and other measuring devices. Typical use is in toolroom, manufacturing floor, and incoming inspection environments where ASME B89.1 compliance is required. The Class ZZ Plus classification makes it appropriate for production inspection of commercial-tolerance parts.

Compatibility

Designed for go inspection of holes at 0.205-inch nominal diameter and for use as a setting standard for micrometers, verniers, and other measuring devices, as noted in the product application data.

Installation Notes

Plug gages are handled and used by quality technicians and toolroom personnel following calibration and metrology procedures. Store the gage in its protective case when not in use to prevent surface damage and corrosion. Clean contact surfaces before each use; do not force the gage into a hole, as this can damage the gage member and invalidate the tolerance. Calibration intervals should follow shop quality management system requirements in accordance with ASME B89.1.
