Vermont Gage 361152030 Threaded Ring Gage 3/4-10 Unc

Product Description

The VERMONT GAGE 361152030 is a No Go threaded ring gage used to verify external thread conformance on fasteners and threaded components. Manufactured from tool steel, this single-ring gage is designed for Class 2A UNC thread inspection at a 3/4-10 thread size. It checks that mating threads do not exceed maximum material condition, ensuring assembled joints meet dimensional tolerance requirements. Licensed machinists, quality technicians, and precision tool inspectors use this gage in production and inspection environments where thread fit and tolerance compliance are critical to assembly integrity.

This gage is used in machining, manufacturing, and mechanical assembly operations where 3/4-10 UNC external threads must be verified against Class 2A tolerance limits. The No Go member confirms that threads are not oversized or out of tolerance. It is well suited for incoming inspection, in-process quality control, and final inspection workflows in both job shop and production floor settings where thread accuracy directly affects fastener performance and safety.

Key Features

• No Go ring gage confirms external threads do not exceed Class 2A maximum material limits
• 3/4-10 UNC thread form for standard unified coarse thread inspection
• Single ring design for dedicated No Go inspection without a combined Go member
• Tool steel construction for dimensional stability and wear resistance in production use
• Manufactured to NIST standards for traceable thread inspection accuracy

Compatibility

Designed for inspection of external 3/4-10 UNC Class 2A threaded components including bolts, studs, and threaded shafts produced to unified coarse thread standards.

Installation Notes

Threaded ring gages are used by quality technicians and machinists and require no permanent installation. Store the gage in a clean, dry location and handle it carefully to prevent nicks or damage to the thread form. Do not force the No Go gage onto a conforming thread; if the gage spins freely more than two full turns, the part fails inspection. Periodically check calibration against a setting plug to maintain inspection accuracy.
