Vermont Gage 361120030 Threaded Ring Gage 10-24 Unc

Product Description

The VERMONT GAGE 361120030 is a single-ring threaded ring gage used to verify that an externally threaded fastener or component does not exceed the maximum allowable material condition for a Class 2A fit. As a No Go gage, it confirms that a mating thread is within tolerance by rejecting parts that are oversized or improperly formed. Machined from tool steel, this gage is built for repeated use in production and inspection environments. It is calibrated to NIST-traceable standards, making it appropriate for quality control applications where documented traceability is required.

This gage is intended for inspecting 10-24 UNC external threads to Class 2A tolerances, the most common thread classification for general-purpose fastener applications. It is used in machine shops, manufacturing facilities, and maintenance operations where thread quality must be verified before assembly. The No Go member is used alongside a Go ring gage to complete a full Class 2A thread inspection routine. Machinists, quality technicians, and tool room personnel are the primary users of this gage.

Key Features

• No Go ring gage for Class 2A external thread inspection
• Thread size 10-24 UNC, single-ring design
• Constructed from tool steel for durability and dimensional stability
• Calibrated to NIST-traceable standards for documented quality assurance
• Single-ring format for straightforward Go/No Go inspection workflow

Compatibility

Designed for inspection of 10-24 UNC externally threaded components requiring Class 2A thread tolerance verification.

Installation Notes

Threaded ring gages are precision inspection tools and should be handled with care to avoid damage to the gage threads. Store gages in protective cases away from other metal tooling when not in use. Apply a light coat of clean oil before and after use to prevent corrosion on the tool steel surfaces. Periodic re-certification against NIST-traceable masters is recommended to maintain inspection accuracy over time.
