Vermont Gage 111194600 Class Zz Plus Plug Gage 0.946in

Product Description

The VERMONT GAGE 111194600 is a Class ZZ Plus plug gage used to verify bore and hole diameters to precise tolerances in metrology and quality control applications. Built from tool steel, it measures a nominal diameter of 0.946 inches with a tolerance of 0.0002 inches, making it suitable for high-accuracy Go inspection tasks. The 10 microinch finish on the gaging surface ensures consistent, repeatable contact. Each unit ships with a Certificate of Accuracy traceable to NIST standards, confirming conformance to ASME B89.1. Licensed metrologists, machinists, and quality technicians rely on this gage for production floor and inspection room use.

This plug gage is designed for Go inspection of machined holes and bores where tight dimensional control is required. It is also used to set and verify micrometers, verniers, and other measuring devices. Typical applications include incoming inspection, in-process quality checks, and final part verification in machining, manufacturing, and precision fabrication environments. The 2.0-inch overall length provides a practical handling profile for bench and floor inspection work.

Compatibility

Designed for Go inspection of bored or reamed holes at 0.946 inches nominal diameter; also used to calibrate and set micrometers, verniers, and comparable precision measuring devices in accordance with ASME B89.1.

Installation Notes

Plug gages are handled and used by metrology technicians, quality inspectors, and machinists. Before use, clean the gaging surface and the part bore with a lint-free cloth to remove any chips, oils, or debris that could affect the reading. Apply light, consistent hand pressure when inserting the gage — never force it into a bore, as this can damage both the gage and the workpiece. Store the gage in its protective case away from temperature extremes to preserve dimensional accuracy.
