Vermont Gage 361144510 Threaded Ring Gage 9/16-18 Unf

Product Description

The VERMONT GAGE 361144510 is a Go-type threaded ring gage designed to verify the maximum material condition of external threads. Built from tool steel, this single-ring gage is used to confirm that a 9/16-18 UNF male-threaded part will assemble correctly with a mating component. A Go gage that passes over the thread confirms the part is within the upper tolerance limit for Class 2A fit. Manufactured to NIST-traceable standards, this gage delivers the dimensional accuracy required for production inspection and incoming quality control work. Machinists, quality technicians, and tool-and-die professionals rely on this type of gage as part of a standard go/no-go inspection routine.

This gage is suited for inspecting externally threaded fasteners, fittings, and machined components with a 9/16-18 UNF thread form. Class 2A is the most common tolerance class for general-purpose inch fasteners, making this gage applicable across a wide range of manufacturing, maintenance, and assembly environments. It is appropriate for both production-floor use and toolroom inspection of parts where thread fit and function must be confirmed before assembly.

Key Features

• Go-type ring gage confirms external thread is within Class 2A maximum material condition
• Thread size 9/16-18 UNF for general-purpose unified fine-thread applications
• Single-ring construction for straightforward pass/fail inspection
• Tool steel construction for durability and wear resistance in production environments
• Manufactured to NIST-traceable standards for reliable dimensional accuracy

Compatibility

Designed for inspection of externally threaded parts with a 9/16-18 UNF thread form and Class 2A tolerance classification. Used as a Go gage in a standard two-gage go/no-go inspection set for unified fine-thread external threads.

Installation Notes

Threaded ring gages are handled and used by quality technicians and machinists — not installed in a mechanical system. Store the gage in its case when not in use to prevent damage to the thread form. Do not force the gage onto a part; if the Go gage does not pass under hand pressure, the part is out of tolerance. Periodic re-calibration against NIST-traceable masters is recommended to maintain inspection accuracy over time.
