Vermont Gage 361115040 Threaded Ring Gage 6-32 Unc

Product Description

The VERMONT GAGE 361115040 is a No Go threaded ring gage designed to verify that externally threaded fasteners and components do not exceed the maximum material condition for a 6-32 UNC thread form. Manufactured from tool steel to maintain dimensional stability under repeated use, this single-ring gage is built to Class 3A tolerance standards and calibrated to NIST-traceable references. It is used in quality control and inspection workflows to reject parts that fall outside specified thread limits. Inspectors, machinists, and quality technicians in manufacturing and assembly environments rely on this type of gage for fast, reliable go/no-go thread verification.

This gage is suited for inspecting 6-32 UNC externally threaded parts in production, incoming inspection, or field verification settings. The No Go ring confirms that a threaded feature has not been cut undersize or oversize beyond the Class 3A fit allowance. It is appropriate for light-duty fastener applications where close thread fit and consistent engagement are required. Single-ring design allows focused No Go testing when paired with a separate Go ring gage.

Key Features

• No Go classification confirms threads do not exceed maximum material condition for 6-32 UNC
• Class 3A tolerance for close-fit thread inspection in precision fastener applications
• Tool steel construction provides wear resistance and dimensional stability
• NIST-traceable standards compliance supports quality system documentation
• Single-ring format allows independent No Go verification

Compatibility

Designed for inspection of externally threaded 6-32 UNC fasteners and components requiring Class 3A thread verification.

Installation Notes

Thread ring gages are used by machinists, quality inspectors, and metrology technicians — not installed in a system, but handled with care to preserve calibration. Keep the gage clean and lightly oiled when not in use to prevent corrosion of the tool steel. Do not force the ring onto a threaded part; a properly rejected No Go gage should not thread fully onto a conforming part. Store in a protective case away from impact and temperature extremes to maintain dimensional accuracy.
