Vermont Gage 361000000 Thread Ring Gage 7/16-14 Unc 3A

Product Description

The VERMONT GAGE 361000000 is a NoGo (Minus) thread ring gage designed to inspect the pitch diameter and functional thread of externally threaded products. Built to 3A class-of-fit tolerances, this gage confirms that a threaded fastener or component does not exceed the maximum material condition - meaning a conforming part should not pass through the NoGo ring. Each gage ships with a certificate of accuracy and is marked with nominal size, threads per inch, class of fit, and pitch diameters, giving technicians immediate traceability at the point of use.

This gage is used in manufacturing, machining, and quality-control environments where 7/16-14 UNC external threads must be verified to specification. It is suited for incoming inspection, in-process checks, and final acceptance of threaded fasteners, fittings, shafts, and hardware. Machinists, quality technicians, and tool room personnel working to inch-series thread standards will use this gage as part of a Go/NoGo functional gauging routine.

Key Features

• NoGo (Minus) ring gage rejects parts that exceed maximum material condition on external threads
• Conforms to 3A class-of-fit tolerances for 7/16-14 UNC thread form
• Supplied with a certificate of accuracy for traceability and quality records
• Marked with nominal size, threads per inch, class of fit, and pitch diameters
• Optional custom marking up to 25 characters available at no additional cost

Compatibility

Designed for functional inspection of 7/16-14 UNC Class 3A externally threaded components. Intended for use as part of a Go/NoGo thread ring gage set for inch-series unified coarse thread applications.

Installation Notes

Thread ring gages are handled and stored by quality technicians and tool room personnel - they are gauging instruments, not installation hardware. Keep the gage clean and lightly oiled when not in use to prevent corrosion. Do not force the gage onto a threaded part; a NoGo ring that passes freely indicates an out-of-tolerance condition. Gage calibration should be verified periodically against a setting plug in accordance with your facility's metrology program.
