The JBO Thread Ring Gauge (GO) - Metric Coarse - Right Hand - 6h - M18 x 2.5 is a precision tool for verifying external threads on metric fasteners and components. Designed for engineers, machinists, quality teams, and assembly professionals, this GO gauge provides fast, reliable checks to ensure parts meet the M18 x 2.5 specification and fit correctly with mating components.

Crafted from hardened steel for exceptional durability, the gauge resists wear through repeated inspections in demanding workshop environments, helping you maintain accurate thread dimensions over time. The intuitive design supports quick setup and consistent results, making it a dependable choice for daily use in manufacturing, automotive, and fabrication settings.

• Precise Go size for fast, reliable checks: The GO side is machined to the exact M18 x 2.5 coarse thread specification, enabling quick pass/fail inspections of external threads and reducing inspection time.
• Hardened steel construction for long-lasting wear resistance: Built to withstand daily handling and contact with metal parts, maintaining dimensional stability across thousands of uses.
• Right-hand, metric coarse compatibility for broad utility: Specifically matched to common M18x2.5 coarse-thread applications, supporting reliable checks on a wide range of fasteners and threaded components.

Using the JBO GO thread ring gauge helps you confirm proper thread fit quickly, reduce rework, and lower downtime by catching mismatches at the source. It streamlines quality control workflows, supports consistent results across batches, and provides confidence that every threaded connection will assemble as intended with standard mating parts.
