Introducing the JBO Thread Ring Gauge (GO) – Metric Fine, Right Hand, 6g, M122 x 1.5. This Go gauge helps engineers, machinists, quality inspectors, and workshop teams verify external thread diameters quickly and reliably, ensuring components meet exacting standards. Crafted from hardened steel, it delivers durable, wear-resistant performance that stands up to demanding environments, while its GO-only design makes it easy to identify properly threaded parts at a glance.

• Precise GO gauge for metric fine threads: Quickly verify external threads against the M122 x 1.5, right-hand, 6g standard, enabling fast pass/fail decisions during inspection.
• Durable hardened steel construction: Built to resist wear and deformation, helping maintain accurate measurements across many uses in busy workshops.
• Easy, go/no-go style inspection: Straightforward design supports quick checks with minimal setup, improving throughput and reducing guesswork in quality control.

Using the JBO Thread Ring Gauge streamlines your QC workflow by delivering reliable, repeatable results. It helps prevent incorrect assemblies, reduces rework, and speeds up inspections, so you can maintain consistent quality across batches and projects with confidence.
