Vermont Gage 112116440 Class Zz Plus Plug Gage 16.44mm

Product Description

The VERMONT GAGE 112116440 is a Class ZZ Plus plug gage designed for precision dimensional inspection of machined bores and holes at 16.44 mm nominal diameter. Built from tool steel with a 10 micro finish, this gage delivers a tolerance of 0.00508 mm, meeting the demands of quality control environments where tight measurement accuracy is required. It ships with a Certificate of Accuracy traceable to NIST, providing documentation support for ISO-compliant and audited inspection programs. Machinists, quality technicians, and metrology professionals use this gage for Go-side attribute inspection to verify that a bore meets its minimum acceptable size before parts advance through production.

This plug gage is suited for use in manufacturing inspection stations, tool rooms, and calibration labs. It is appropriate for Go inspection tasks and can also serve as a reference standard when setting micrometers, verniers, and other measuring devices. At 2.0 inches overall length, it is compact enough for benchtop use and easy handling during high-volume part checks. Typical applications include incoming inspection, in-process quality control, and final acceptance inspection of machined components in automotive, aerospace, and general manufacturing environments.

Compatibility

Designed for Go inspection of bores at 16.44 mm nominal diameter and for setting micrometers, verniers, and other measuring devices requiring a traceable reference standard.

Installation Notes

Plug gages are handled and used by quality technicians and machinists and do not require mechanical installation. Keep the gage clean and lightly oiled when not in use to prevent corrosion on the tool steel body. Do not force the gage into a bore; if resistance is felt beyond normal snug fit, inspect the bore for burrs or out-of-tolerance conditions. Store in a protective case away from temperature extremes to preserve calibration integrity.
