The JBO Thread Ring Gauge GO — Metric Coarse (Right Hand, 6g) is a precision inspection tool designed to verify external metric coarse threads, including M2 x 0.4. It’s ideal for quality control, manufacturing, and maintenance environments where fast, reliable thread validation matters.

Built from hardened steel, this GO gauge delivers durability and wear resistance for busy workshops. Its exact machining and straightforward use help teams quickly confirm that threaded components meet the required size and pitch so they fit and function as intended.

• Durable hardened steel construction: Built to withstand daily use in busy inspection environments, providing long-lasting wear resistance and consistent measurements.
• Precise metric coarse GO specification (M2 x 0.4): Machined to exact GO dimensions for quick, reliable pass/fail checks on external threads, ensuring parts meet the M2 x 0.4 standard.
• User-friendly, right-hand design: Easy to align and insert during setup, helping reduce inspection time and minimize handling errors on the shop floor.

With the JBO GO Thread Ring Gauge in your QC toolkit, you can accelerate inspections, reduce rework, and maintain consistent results across production runs. Quick, clear GO checks help ensure proper thread mating, improve workflow efficiency, and build confidence that parts will perform as intended in the final assembly.
