Vermont Gage 361121040 Threaded Ring Gage 10-32 Unf

Product Description

The VERMONT GAGE 361121040 is a single-ring threaded ring gage used to verify that an externally threaded fastener or component does not exceed the maximum material condition for its thread class. Manufactured from tool steel, this No Go gage is ground and set to Class 3A tolerance limits per UNF standards, making it a reliable go-to instrument for quality control inspections in machining, assembly, and precision fabrication environments. Inspectors and tool room technicians use ring gages like this one to confirm that a threaded part will not assemble with a mating component beyond its allowable tolerance boundary.

This gage is suited for inspecting 10-32 UNF external threads on fasteners, studs, shafts, and machined components in industrial and manufacturing settings. The No Go ring gage is used as part of a two-gage inspection process alongside a Go ring gage. When the No Go gage cannot be turned onto the thread by hand, the part is within acceptable tolerance. Applications include aerospace, automotive, and general mechanical assembly where tight thread tolerance verification is required.

Key Features

• No Go classification confirms threads do not exceed maximum material condition for Class 3A UNF tolerance
• 10-32 UNF thread size for fine-pitch external thread inspection
• Single ring design for straightforward go/no-go inspection workflows
• Tool steel construction provides wear resistance and dimensional stability
• Calibrated to NIST-traceable standards for inspection confidence

Compatibility

Designed for inspection of 10-32 UNF Class 3A external threads. Intended for use as part of a standard two-gage (Go and No Go) thread inspection set for fine-pitch unified national threads.

Installation Notes

Thread ring gages are inspection instruments and should be handled by qualified inspection or tool room personnel. Store the gage in a clean, dry environment away from chips, coolant, and abrasive debris to preserve calibration. Never force the gage onto a thread — apply by hand only with no tools. Periodic re-calibration against NIST-traceable masters is recommended to maintain measurement integrity.
