Vermont Gage 301000000 Taperlock Thread Plug Gage

Product Description

The VERMONT GAGE 301000000 is a Taperlock-style thread plug gage designed to inspect the pitch diameter and functional thread form of internal threaded components. This NoGo (Minus) member is used in the go/no-go gaging process to verify that a 1 1/4-7 UNC 2B threaded hole does not exceed the maximum allowable material condition. The gage features a NoGo length of 0.75 inches and a NoGo pitch diameter of 1.1668 inches. It ships with a certificate of accuracy and is permanently marked with nominal size, threads per inch, class of fit, and pitch diameter values. Machinists, quality control technicians, and precision manufacturing shops use this gage in production and inspection environments.

This gage is appropriate for inspecting 1 1/4-7 UNC Class 2B internal threads in residential, commercial, and industrial manufacturing or maintenance settings. The Taperlock design allows the gage member to be mounted in a standard Taperlock handle, which is sold separately. It is well suited for use on the shop floor or in a metrology lab where thread conformance to unified inch standard tolerances must be confirmed before assembly.

Installation Notes

Thread plug gages are installed and used by machinists, quality technicians, or tool room personnel. Before use, seat the Taperlock gage member securely into an appropriately sized Taperlock handle. Keep the gage clean and free of chips, coolant residue, and burrs that could affect measurement accuracy. Do not force the NoGo member into a threaded hole; proper gaging technique requires hand pressure only.
