The JBO Thread Ring Gauge (GO) – Metric Fine, Right Hand, 6g, M5 x 0.75 is a precision tool designed to verify external thread diameters quickly and reliably. It’s an essential companion for engineers, machinists, and QC teams who need to confirm that threaded components conform to the M5 x 0.75 pitch and the 6g tolerance.

Manufactured from hardened steel for durability, this GO ring gauge resists wear in busy workshops, delivering long-lasting accuracy. Its simple ring design makes it easy to identify passing components at a glance, supporting fast, repeatable inspections across production runs.

• Precise metric fine threading (M5 x 0.75, 6g): Enables quick, reliable checks of external thread diameter and pitch to confirm compliance with essential standards.
• Durable hardened steel construction: Withstands daily use in demanding environments, maintaining accuracy and reducing replacement costs.
• Easy pass/fail inspection: GO design delivers fast, unambiguous results, speeding up quality control and minimizing production downtime.

Using the JBO GO Ring Gauge for metric fine threads provides a reliable reference during manufacturing, repair, and batch QA. It helps catch tolerance issues early, shortens setup and inspection times, and supports consistent performance across threaded components, giving you confidence in every fit.
