Vermont Gage 361153040 Threaded Ring Gage 3/4-16 Unf

Product Description

The VERMONT GAGE 361153040 is a single-ring threaded ring gage used to verify that an externally threaded workpiece does not exceed the maximum material condition for a 3/4-16 UNF Class 3A thread. As the No Go member of a Go/No Go gage set, it confirms that a threaded part has not been cut undersize or outside tolerance. Machined from tool steel to maintain dimensional stability under repeated use, this gage is a standard inspection tool on production floors, machine shops, and maintenance operations where thread-fit verification is required before assembly.

This gage is suited for inspecting 3/4-16 UNF external threads to Class 3A tolerance, the tightest standard fit class for unified threads. It is used by machinists, quality control inspectors, and maintenance technicians in manufacturing, aerospace, automotive, and industrial maintenance settings. A No Go ring gage is typically paired with a Go ring gage for complete thread verification per standard inspection practice.

Key Features

• No Go member for 3/4-16 UNF Class 3A thread inspection
• Single-ring design for straightforward pass/fail verification
• Tool steel construction for durability and dimensional stability
• Manufactured to NIST-traceable standards
• Confirms external threads do not exceed maximum material condition

Compatibility

Designed for use with externally threaded fasteners and components cut to 3/4-16 UNF Class 3A thread specifications. Typically paired with a matching 3/4-16 UNF Class 3A Go ring gage for complete thread inspection.

Installation Notes

Thread ring gages are inspection instruments, not cutting or forming tools. Handle with care to avoid dropping or striking the gage, which can alter calibration. Clean threads on both the gage and the workpiece before use. Periodic re-calibration against NIST-traceable masters is recommended to maintain inspection accuracy.
