Vermont Gage 361121020 Threaded Ring Gage 10-32 Unf

Product Description

The VERMONT GAGE 361121020 is a Go-type threaded ring gage used to verify that external threads meet the minimum acceptable tolerance for functional assembly. Designed for 10-32 UNF threads to Class 3A tolerances, this single-ring gage confirms that a threaded fastener or component will assemble correctly with its mating part. Manufactured from tool steel, it delivers the hardness and wear resistance required for repetitive inspection use in a production or shop environment. Licensed machinists, quality technicians, and precision thread inspectors are the primary users of this gage.

This gage is suited for inspection of 10-32 UNF externally threaded parts in manufacturing, machining, and assembly applications. Class 3A is the tightest standard tolerance class for inch unified external threads, making this gage appropriate where close-tolerance fastener fit is critical. It is commonly used on the shop floor, in receiving inspection, and in tool-and-die environments where thread conformance must be documented. The single-ring Go gage is typically used alongside a No-Go gage to perform a complete thread inspection routine per standard gaging practice.

Key Features

• Go-type ring gage verifies minimum material condition of 10-32 UNF external threads
• Class 3A tolerance classification for close-tolerance thread inspection
• Single-ring design for focused Go-function verification
• Tool steel construction provides hardness and dimensional stability under repeated use
• NIST-traceable standards compliance supports documented quality systems

Compatibility

Designed for inspection of externally threaded components with a 10-32 UNF thread form to Class 3A tolerance. Use with a matching No-Go ring gage to complete a full attribute thread inspection per standard gaging procedure.

Installation Notes

Threaded ring gages are used by quality technicians and machinists and do not require installation in the traditional sense. Store the gage in its protective case when not in use to prevent damage to the thread form. Handle with clean, dry hands or lint-free gloves to prevent corrosion from skin contact. Periodically verify the gage against a setting plug or calibration standard to confirm it remains within tolerance for continued use.
