The JBO Thread Ring Gauge (GO) for UNC right-hand threads, size No. 10 x 24, is a dedicated tool for quickly validating external thread diameters to the Unified National Coarse standard. Designed for engineers, buyers, machinists, and quality professionals, this GO gauge provides a reliable pass/fail reference that confirms parts meet the required 2A class tolerances.

Built to endure busy workshops, the gauge is crafted from hardened steel for outstanding wear resistance and long-lasting accuracy. Its straightforward design makes it easy to read and use during routine inspections, helping you verify conformance without guesswork.

• Precise UNC external thread verification: Quickly confirm that No. 10 x 24 right‑hand threads meet the 2A tolerance using the GO limit, reducing inspection time and rework.
• Rugged hardened-steel construction: Built to resist wear in demanding environments, preserving accuracy and extending service life across thousands of gauging cycles.
• User-friendly QC reading: Clear GO indication simplifies pass/fail decisions, speeding up quality checks and supporting consistent results in production or maintenance settings.

This gauge helps you streamline your quality control workflow by delivering a reliable, repeatable measurement reference for UNC threads. By quickly validating components at the source, it minimizes downtime, reduces the risk of incorrect assemblies, and supports precise, standards-compliant manufacturing across projects.
