Vermont Gage 301000000 Thread Plug Gage 10-32 Unf

Product Description

The VERMONT GAGE 301000000 is a NoGo (Minus) Taperlock thread plug gage designed to inspect the pitch diameter and functional thread of internally threaded workpieces. Built to 10-32 UNF 3B specifications, this gage verifies that an internal thread does not exceed the maximum material condition - rejecting out-of-tolerance parts before they reach assembly. The Taperlock design allows the gage member to be mounted in a standard Taperlock handle, which is sold separately. Each gage ships with a certificate of accuracy and is marked with nominal size, threads per inch, class of fit, and pitch diameters. Machinists, quality inspectors, and toolroom technicians use this type of gage in production and incoming inspection workflows.

This NoGo thread plug gage is suited for inspecting 10-32 UNF Class 3B internal threads in precision fastener applications, aerospace, electronics, and general machining environments where close-tolerance unified fine threads are specified. The 3B class designation indicates a standard tolerance class for unified internal threads. One line of additional custom marking up to 25 characters can be added at no extra charge, which is useful for shop-floor traceability and tool crib identification.

Key Features

• Inspects pitch diameter and functional thread of 10-32 UNF 3B internal threads
• NoGo (Minus) member rejects threads that exceed maximum material condition
• Taperlock shank fits standard Taperlock gage handles for quick member changes
• Supplied with a certificate of accuracy for traceability
• Marked with nominal size, TPI, class of fit, and pitch diameters per standard practice
• Optional custom marking up to 25 characters available at no additional cost

Compatibility

Designed for use with standard Taperlock-style gage handles sized for small-diameter thread plug gage members. Intended for inspection of 10-32 UNF Class 3B internal threaded components per unified thread standard specifications.

Installation Notes

Thread plug gages are installed and removed by quality technicians or machinists using a compatible Taperlock handle - no special tools are required beyond the handle itself. Before use, ensure the gage and workpiece threads are clean and free of chips, oil, or debris that could affect measurement accuracy. Do not force the NoGo member into a thread; if it enters with normal hand pressure, the thread is out of tolerance. Periodic recalibration against traceable standards is recommended to maintain measurement integrity.
