The JBO Thread Ring Gauge (GO) is a precision tool designed to verify external metric threads quickly and reliably. It’s ideal for machinists, quality inspectors, engineers, and assembly technicians who need a straightforward go/no-go check to confirm threaded components meet exact standards.

Built for metric fine threads with right-hand orientation (M64 x 2) and a 6g tolerance, this gauge blends accuracy with lasting durability. Crafted from hardened steel, it resists wear in busy workshops, delivering reliable performance through thousands of inspections.

• Precise GO verification for metric fine threads: Quickly confirm that external threads meet M64 x 2, 6g, right-hand specifications, enabling fast pass/fail decisions and reducing rework.
• Hardened steel construction for durability: Built to withstand daily use in busy environments, maintaining accuracy over many cycles and resisting wear from handling and cleaning.
• Clear, fast identification for quality control: Easy-to-read indicators and straightforward go/no-go checks help operators identify conforming parts at a glance, boosting throughput and consistency.

Using the JBO Thread Ring Gauge (GO) in your QC process helps standardize inspections, shorten cycle times, and improve overall thread reliability across batches. Its durable build and precise metric fine specification reduce downtime from failed inspections and ensure components fit correctly in final assemblies, delivering consistent performance from the shop floor to the field.
