Vermont Gage 301000000 Taperlock Thread Plug Gage

Product Description

The VERMONT GAGE 301000000 is a Go (Plus) Taperlock Thread Plug Gage designed to inspect the pitch diameter and functional thread of internal threaded products. Built to the Taperlock handle system, this gage member checks that an internally threaded part accepts a mating fastener within the specified tolerance range. It is manufactured to a 3/8-24 UNF thread form and is suitable for Class 2B and 3B fits. The Go length measures 0.75 inches with a Go pitch diameter of 0.3479 inches. Thread plug gages of this type are standard tools for machinists, quality control technicians, and precision manufacturing shops.

This gage is used in manufacturing and inspection environments where 3/8-24 UNF internal threads must be verified for conformance to Class 2B or 3B fit standards. Typical applications include aerospace, automotive, and general industrial production lines where threaded hole acceptance criteria must be documented. The gage ships with a certificate of accuracy and is marked with nominal size, threads per inch, class of fit, and pitch diameters. One line of additional custom marking up to 25 characters is available at no added cost.

Installation Notes

Thread plug gages are handled and used by quality control technicians and machinists in inspection settings. No power source or torque tools are required. Gages should be stored in a clean, dry environment and handled with care to prevent damage to the thread form. Periodic calibration against certified masters is recommended to maintain measurement traceability.
