The JBO Thread Ring Gauge (GO) – Metric Fine, Right Hand, M20 x 1.25 is a precision Go gauge used to quickly verify external thread dimensions against exact standards. Ideal for quality control, machine shops, and maintenance teams, it helps confirm that a component’s thread diameter and pitch match the specified M20 x 1.25 fine thread.

Crafted from hardened steel, this GO gauge delivers rugged durability for busy workshops, maintaining accurate checks even after repeated use and in challenging environments.

• Fast, go/no-go verification: Quickly confirm that external threads meet the M20 x 1.25 metric fine specification, speeding inspections and reducing downtime.
• Durable hardened steel construction: Built to resist wear and keep its accuracy over many cycles in demanding shop conditions.
• Right-hand, metric fine compatibility: Optimized for standard right-hand threads, ensuring trustworthy measurements across common components and assemblies.

Using this gauge in your QA and assembly workflow helps ensure consistent part quality, minimizes rework, and supports reliable interchange with suppliers. By delivering repeatable results, it boosts confidence in fit, finish, and overall performance of threaded assemblies.
