Vermont Gage 111120900 Class Zz Plus Plug Gage 0.209 in

Product Description

The VERMONT GAGE 111120900 is a Class ZZ Plus plug gage designed to verify bore and hole diameters in precision machining and inspection environments. It measures 0.209 inches in diameter with a tolerance of 0.0002 inches, making it suited for go-inspection applications where dimensional accuracy is critical. The overall length is 2.0 inches. Manufactured from tool steel with a 10 microfinish surface, this gage delivers consistent, repeatable measurements. Each unit ships with a Certificate of Accuracy with NIST Traceability, meeting the documentation requirements of quality systems in production and metrology settings.

This plug gage is used in go inspection routines to verify that a hole or bore meets its minimum acceptable size. It is appropriate for use alongside set micrometers, verniers, and other precision measuring devices on the shop floor or in a metrology lab. Typical users include machinists, quality technicians, and tool room professionals working in manufacturing environments where dimensional compliance is required. The Class ZZ Plus designation indicates it meets ASME B89.1 standards for gage tolerancing.

Installation Notes

Plug gages are handled and used by quality technicians and machinists; no installation in the traditional sense applies. Ensure the gage and workpiece are at a stable ambient temperature before use to avoid thermal expansion errors. Clean the gage and bore thoroughly before gaging to prevent false readings or surface damage. Store the gage in its protective case when not in use to preserve the 10 microfinish surface and dimensional integrity.
