The JBO Thread Ring Gauge (NoGo) – Metric Fine, Right Hand, 6g, M135 x 1.5 is a precision tool designed to verify external thread diameters with speed and reliability. It is ideal for inspectors, machinists, engineers, and quality teams who need a straightforward, repeatable check to ensure parts meet exact thread specifications. Built to withstand daily use, this NoGo gauge helps you quickly confirm that threaded components are within the required tolerance before assembly or maintenance.

• Clear NoGo verification: A simple, unambiguous check that quickly identifies non-conforming external threads so you can reject out-of-tolerance parts at the first point of inspection.
• Durable hardened steel construction: Built to resist wear and maintain accuracy even in busy workshops, reducing replacement costs and downtime.
• Metric Fine, M135 x 1.5, right-hand alignment: Precisely matched to common metric fine-thread specs, ensuring consistent, repeatable measurements across parts and jobs.

Using this ring gauge streamlines your quality workflow: it delivers fast, repeatable checks of external thread diameters, minimizes guesswork, and helps you capture consistent measurement data for audits and traceability. The robust design reduces downtime and replacement costs, while the precise alignment with M135 x 1.5 threads supports reliable, repeatable results across assemblies and maintenance tasks.
