The JBO Thread Ring Gauge (NoGo) is a precision inspection tool designed to verify external metric threads. It’s ideal for manufacturers, engineers, inspectors, and quality teams working with metric fine threads, helping you quickly confirm that parts meet the required diameter limits for reliable fit and performance.

Crafted for durability, this gauge uses hardened steel to withstand daily use in busy workshops and production lines. It targets the M72 x 1.5, 4h, right-hand thread specification, delivering stable, repeatable NoGo checks that remain accurate over time.

• Precise metric NoGo verification for M72 x 1.5 (4h, Right Hand): Quickly confirms external thread diameter is within the maximum limit and flags out‑of‑tolerance parts, speeding QC decisions and reducing scrap.
• Hardened steel construction for durability: Built to endure daily shop use and resist wear, ensuring long‑lasting, reliable measurements in demanding environments.
• User‑friendly design for fast inspections: Easy orientation and repeatable checks that minimize setup time and integrate smoothly into existing quality‑control workflows.

Using the JBO NoGo Ring Gauge helps standardize thread inspections, improve first‑pass yield, and maintain consistent quality across production runs. Its robust build and precise dimensions translate into fewer reworks, faster throughput, and increased confidence in every measurement.
