The JBO Thread Ring Gauge (NoGo) is a precision tool designed to verify external metric threads with reliability and speed. Specifically configured for right-hand threads and metric fine pitches, it is ideal for engineers, machinists, inspectors, and assembly teams who need to confirm that threaded components meet exact specifications, such as M38 x 1.5 with a 6h tolerance.

Crafted from hardened steel, this NoGo ring gauge offers exceptional durability and wear resistance for busy workshops and production lines. Its precise dimensions support efficient inspection, helping you quickly distinguish conforming parts from out-of-tolerance components and maintain consistent quality across your projects.

• NoGo Gauge for Metric Fine Threads: Quickly determines if external threads, like M38 x 1.5, are within the NoGo limit, enabling fast, clear pass/fail decisions and reducing rework in QC inspections.
• Hardened Steel Construction: Built to endure daily use in demanding environments, delivering long life and stable measurements even after repeated insertions and removals.
• Right-Hand, 6h Configuration: Specifically tuned for right-hand metric fine threads with 6h tolerance, ensuring reliable, straightforward checks that align with common manufacturing standards.

Using the JBO Thread Ring Gauge streamlines quality control by delivering precise, repeatable checks that fit seamlessly into your inspection routine. It helps shorten inspection times, improve part conformity, and support dependable results across production, assembly, and maintenance workflows.
