Vermont Gage 112301610 Class Zz Plus Plug Gage 1.61mm

Product Description

The VERMONT GAGE 112301610 is a Class ZZ Plus plug gage designed for precise dimensional inspection of small bores and holes. Built from tool steel with a 10 microfinish surface, this gage provides reliable go-inspection capability with a tolerance of 0.00508 mm. At 2.0 inches overall length, it is sized for easy single-hand use in shop and lab environments. Each unit ships with a Certificate of Accuracy traceable to NIST, meeting the documentation requirements of quality management systems that follow ASME B89.1 standards. Licensed metrologists, quality technicians, and precision machinists rely on this type of gage for verifying machined hole diameters against print tolerances.

This plug gage is suited for go inspection tasks across manufacturing, toolroom, and metrology lab settings. It is used with micrometers, verniers, and other measuring devices to verify bore conformance during production and incoming inspection. The 1.61 mm diameter targets small-bore applications common in precision machined components, medical device manufacturing, and tight-tolerance assembly work. Its compact form factor makes it practical for bench inspection as well as in-process checks on the production floor.

Key Features

Compatibility

Designed for use as a go plug gage in applications requiring inspection of 1.61 mm diameter bores. Compatible for use alongside micrometers, vernier calipers, and other precision measuring devices in quality inspection workflows.

Installation Notes

Plug gages should be handled by calibration technicians or quality inspection personnel trained in precision measurement practices. Store the gage in its protective case when not in use to prevent surface damage and contamination. Clean the gage surface before each use and allow it to reach ambient temperature to avoid thermal expansion errors. Never force the gage into a bore; apply light, steady hand pressure only.
