The JBO Thread Ring Gauge (NoGo) is a precision tool designed to check external metric coarse threads. Specifically tailored for right-hand M18 x 2.5 threads with a 6g tolerance, it helps inspectors and technicians verify that threaded components meet the required standards and will assemble correctly.

Constructed from hardened steel for durability, this NoGo gauge resists wear and maintains accuracy through repeated use in demanding environments. Its straightforward design makes it easy to identify non-conforming components during quality control, speeding up inspections and reducing rework.

• Accurate metric coarse NoGo verification: Confirms the maximum dimension of M18 x 2.5 threads (6g, right-hand) to ensure components stay within specification and prevent oversized parts from passing inspection.
• Durable hardened steel construction: Built to withstand daily shop use, offering long-lasting wear resistance and reliable performance in busy manufacturing and maintenance settings.
• User-friendly inspection tool: Enables quick, clear pass/fail determinations for threaded parts, helping operators spot non-conforming components at a glance and keep workflows moving.

Using the JBO Thread Ring Gauge NoGo in your quality control processes helps streamline inspections, reduce rework from incorrect threads, and ensure consistent, reliable mating of metric coarse threaded components. The durable construction and straightforward operation give teams confidence that threaded connections will meet required standards, improving overall efficiency and quality across projects.
