The JBO Thread Ring Gauge (NoGo) – Metric Fine for Left-Hand M72 x 1.5 is a precision inspection tool designed to verify external threads on components quickly and reliably. It is ideal for engineers, machinists, quality teams, and maintenance professionals who need to confirm that threaded parts meet the specified maximum diameter and pitch, ensuring consistent assembly and performance.

Made from hardened steel, this NoGo gauge resists wear in demanding shop environments while delivering long-lasting accuracy. The NoGo design provides a clear, quick signal when a thread is outside tolerance, helping you identify non-conforming parts fast and keep production moving smoothly.

• Metric fine NoGo design for M72 x 1.5: Quickly confirms whether external threads stay within the maximum allowed diameter for the M72 x 1.5 fine-pitch range, enabling fast pass/fail decisions during inspection.
• Hardened steel construction: Delivers excellent durability and wear resistance, maintaining accuracy through high-volume use in busy workshops.
• Left-hand thread compatibility and intuitive use: Specifically designed to work with left-hand threads, with straightforward alignment to reduce setup time and inspection errors.

With the JBO Thread Ring Gauge, you gain a reliable, repeatable method to validate thread diameters, speed up quality checks, and document compliance across batches. The durable construction and precise NoGo limit help minimize downtime, improve workflow, and deliver consistent results in manufacturing, maintenance, or repair tasks.
