Vermont Gage 112114980 Class Zz Plus Plug Gage 14.98mm

Product Description

The VERMONT GAGE 112114980 is a Class ZZ Plus cylindrical plug gage used to verify bore and hole diameters in precision machining and quality-control applications. Manufactured from tool steel with a 10 microinch finish, it measures 14.98 mm in diameter with a tolerance of 0.00508 mm, making it suitable for Go inspection work where tight dimensional verification is required. The overall length is 2.0000 inches. Each unit ships with a Certificate of Accuracy traceable to NIST, supporting documentation requirements in calibrated inspection environments. This gage is handled by quality technicians, machinists, and metrologists working to ASME B89.1 standards.

This plug gage is intended for Go inspection use during in-process and final inspection of machined bores, holes, and similar internal features. It is also appropriate for setting and verifying micrometers, verniers, and other measuring devices that require a known reference diameter. Typical environments include machine shops, manufacturing facilities, and inspection labs where repeatable, traceable dimensional verification is part of standard workflow. The 14.98 mm diameter makes it well suited for metric-dimensioned workpieces in both light manufacturing and precision production settings.

Compatibility

Designed for use as a Go plug gage for bore inspection and as a reference standard for setting micrometers, verniers, and other measuring devices requiring a 14.98 mm reference diameter.

Installation Notes

Plug gages are handled and used by quality technicians and machinists — no power tools or utilities need to be shut off prior to use. Store the gage in its protective case when not in use and avoid dropping or contacting hard surfaces to preserve the lapped finish and dimensional integrity. Clean the gage and the bore being checked before use to prevent false readings caused by debris or coolant residue. Periodic recalibration intervals should follow your facility quality plan and applicable ASME B89.1 guidelines.
