The JBO Thread Ring Gauge (NoGo) is a precision inspection tool crafted for metric fine external threads. Specifically designed for right-hand M22 x 1 threads and the 6h class, it helps engineers, inspectors, and machinists quickly verify that parts meet exact standards. Use it in quality checks, assembly preparation, or incoming inspection to ensure components conform before they move to the next stage.

Made from hardened steel, this NoGo gauge delivers reliable performance in busy workshops and demanding environments. Its straightforward design lets you identify non-conforming threaded components at a glance, supporting accurate quality control and reducing rework.

• Precise NoGo gauge for M22 x 1 right-hand threads: Quickly validates external thread diameters against the NoGo limit, helping you confirm parts meet the 6h class specification and catch out-of-tolerance components before they proceed.
• Hardened steel construction for durability: Built to withstand daily use in busy production settings, resisting wear to maintain accurate measurements and extend tool life.
• User-friendly design for fast, reliable QC: Simple to use and easy to interpret—just attempt to thread the ring onto the part to identify non-conforming components and keep workflows moving smoothly.

This gauge supports consistent, high-precision results across batches, speeds up inspections, and gives your team the confidence to make fast, informed quality decisions.
