The JBO Thread Ring Gauge (NoGo) is a precision inspection tool designed to verify external threads to Unified thread standards. It's ideal for manufacturers, automotive shops, aerospace suppliers, and maintenance teams who need fast, reliable checks to prevent mismatches in assemblies.

Sized for UNEF right-hand threads, this gauge features a 1 3/16 inch diameter with 18 threads per inch (1 3/16 x 18) and is crafted from hardened steel for lasting accuracy in demanding environments. The NoGo design provides an unmistakable indication of non-conforming threads, helping inspectors quickly confirm fit and function without counting or guesswork.

• Hardened steel construction for lasting durability: With hardened steel, this gauge resists wear from repeated insertions and removals, maintaining accurate measurements over years of use.
• Accurate UNEF 1 3/16 x 18 Right-Hand 2A sizing for consistent validation: Calibrated to the UNEF external thread standard, including right-hand threads and class 2A, at the 1 3/16 x 18 size, enabling repeatable GO/NO-GO checks across parts and batches.
• Instant No-Go indication for fast inspections: The dedicated NoGo design delivers quick, clear feedback when a thread does not meet specification, speeding up quality control and reducing rework.

When you integrate the JBO NoGo gauge into your workflow, you gain faster, more reliable thread validation, reduce scrap and rework, and improve traceability for audits. Its robust build and precise sizing ensure confidence in every inspection, whether you're screening supplier parts or verifying in-house machined components.
