Vermont Gage 112116540 Class Zz Plus Plug Gage 16.54mm

Product Description

The VERMONT GAGE 112116540 is a Class ZZ Plus cylindrical plug gage machined from tool steel for dimensional inspection of bored holes, machined bores, and precision-fit openings. It measures 16.54 mm in diameter with a tolerance of 0.00508 mm, making it appropriate for go-style inspection tasks where tight dimensional control is required. The overall length is 2.0000 inches. Each unit ships with a Certificate of Accuracy that carries NIST traceability, supporting quality documentation requirements in shop and lab environments. Machinists, quality technicians, and tool-and-die professionals use this gage as a quick, reliable pass-fail check during in-process and final inspection.

This plug gage is suited for go inspection applications in machine shops, manufacturing cells, and metrology labs handling precision components. It is also compatible with setup and verification tasks involving micrometers, verniers, and other measuring devices where a traceable reference standard is needed. The 10 micro coating finish protects the gage surface and helps maintain dimensional stability over repeated use cycles. It is appropriate for both production-floor inspection and bench-top calibration support in light industrial and precision manufacturing settings.

• Conforms to ASME B89.1 standards

Compatibility

Designed for go inspection of 16.54 mm diameter bores and for use as a reference standard with micrometers, verniers, and other measuring devices per ASME B89.1.

Installation Notes

Plug gages are handled and used by quality technicians and machinists — no installation in the traditional sense applies, but proper care procedures are essential. Store the gage in its case when not in use and avoid dropping or contacting hard surfaces that could alter the ground diameter. Clean the gage and the bore with a lint-free cloth before use to prevent debris from causing false readings. Follow your facility's calibration interval policy and retain the included NIST-traceable Certificate of Accuracy for your quality records.
