The JBO Thread Ring Gauge (NoGo) is a precision tool for inspecting external threads. It’s ideal for inspectors, machinists, and quality teams who need fast, reliable verification of M13 x 1.5 right-hand, fine-thread components in the 6h class. The NoGo designation helps you quickly identify undersized or out-of-spec threads during routine quality checks.

Built from hardened steel for lasting durability, this gauge is designed to withstand the rigors of busy workshops and demanding environments. Precise dimensions and sturdy construction ensure consistent results across daily use and audits.

• NoGo verification for undersize threads: Instantly identifies non-conforming components during inspection, reducing rework and delays.
• Right-hand metric fine threading (M13 x 1.5): Provides precise checks for the common external thread form used across many applications.
• Hardened steel construction for durability: Delivers long service life and wear resistance in busy shop environments.

Using this gauge streamlines workflows by enabling quick pass/fail decisions on threaded parts, improving throughput and consistency. It helps maintain tight tolerances, reduces scrap, and supports audits with clear, auditable measurements. Its robust build means fewer tool changes and less downtime, keeping your quality checks moving smoothly from part intake to final assembly.
