The JBO Thread Ring Gauge (GO) – Metric Fine, Right Hand, 6e, M64 x 1.5 is a precision inspection tool for measuring external threads. It helps engineers, machinists, quality inspectors, and assembly teams quickly verify that a thread matches the exact size and pitch required for reliable assembly.

Built from hardened steel for long service life, this GO gauge delivers durable, repeatable go/no-go checks in demanding workshop environments, ensuring components meet strict standards before they move to the next stage of production.

• Precise GO measurement for Metric Fine threads: Quickly verify external thread Ø and pitch for M64 x 1.5, delivering clear go/no-go results to speed up inspection and ensure proper fit during assembly.
• Durable hardened steel construction: Resistant to wear and corrosion, delivering consistent performance and long service life in busy workshop environments.
• User-friendly, fast QC tool: Simple handling and alignment make it easy to identify properly conforming components at a glance, reducing inspection time and training needs.

With the JBO GO gauge, you gain reliable, repeatable checks that support tight tolerances and consistent assembly results. Its robust construction minimizes downtime due to wear, while its straightforward operation helps teams complete quality checks faster, improving workflow, reducing rework, and enhancing overall production reliability.
