Vermont Gage 111124700 Class Zz Plus Plug Gage 0.247 in

Product Description

The VERMONT GAGE 111124700 is a Class ZZ Plus plug gage used to verify bore and hole dimensions to a nominal diameter of 0.247 inches. Manufactured from tool steel, it delivers a surface finish of 10 microfinish and holds a tolerance of 0.0002 inches, meeting the dimensional accuracy requirements of ASME B89.1. Total overall length is 2.0 inches. Each unit ships with a Certificate of Accuracy with NIST traceability, making it ready for use in calibrated measurement environments. Machinists, quality control technicians, and metrology professionals use this type of gage for go inspection and for setting and verifying micrometers, verniers, and other precision measuring devices.

This plug gage is suited for use in production inspection, tool room environments, and calibration labs where close-tolerance bore verification is required. Class ZZ Plus gages are appropriate for checking finished holes in both light manufacturing and precision machining applications. The included NIST-traceable certificate supports documentation requirements in ISO and AS9100-registered facilities. Installation or use does not require fixturing beyond hand application against the measuring device or bore being checked.

Key Features

Compatibility

Designed for go inspection use with bore gauges, and for setting micrometers, verniers, and other precision measuring devices requiring a 0.247-inch reference standard.

Installation Notes

This gage is a hand-held precision instrument and requires no permanent installation. Handle with clean, dry hands or lint-free gloves to prevent corrosion from skin oils. Store in the provided case or a protected environment when not in use. Do not use the gage as a mechanical stop or force it into undersized bores, as this can alter the gage surface and compromise measurement accuracy.
