The JBO Thread Ring Gauge (NoGo) – Metric Fine, Right Hand, 6g – M128 x 1.5 is a precision tool designed to verify external thread diameters with speed and certainty.

It’s ideal for engineers, machinists, inspectors, and workshop professionals who need to confirm that threaded parts meet exact standards.

• Hardened steel construction: Built to resist wear and deliver long service life in tough shop environments, ensuring consistent measurements over time.
• Precise metric fine NoGo gauge (M128 x 1.5, right-hand): Delivers reliable diameter verification for the specified thread, helping you quickly identify parts that are out of tolerance.
• User-friendly inspection design: Easy to read and use, enabling fast, confident QC checks and reduced downtime in production lines.

Using this gauge, your workflow becomes faster and more predictable: quick pass/fail checks keep production moving, minimize rework, and help you meet tight tolerances with confidence. The combination of hardened steel durability and precise sizing delivers reliable performance over many jobs, so you can trust thread measurements across daily use and routine inspections.
