The JBO Thread Ring Gauge (GO) - Metric Coarse - Right Hand - 6h - M45 x 4.5 is a precision tool built to quickly and reliably verify external metric coarse threads. It’s ideal for machinists, quality inspectors, and assembly teams who need confident, repeatable pass/fail checks to ensure parts thread correctly with mating components.

• Precision GO gauge for metric coarse threads: Quickly confirm the correct major diameter and pitch for M45 x 4.5 coarse threads, enabling fast, reliable pass/fail verification during incoming, in-process, and final inspection.
• Rugged hardened steel construction: Crafted from durable hardened steel to resist wear, maintain dimensional integrity, and provide long service life in demanding workshop environments.
• User-friendly, repeatable inspections: Designed for straightforward use with clear, consistent results, reducing inspection time and minimizing rework due to ambiguous measurements.

With the JBO GO thread gauge, you’ll streamline quality control, speed up threaded-connection verification, and ensure reliable performance across production runs. Its robust build and precise geometry support consistent results, helping you meet industry standards and minimize downtime in busy fabrication and assembly environments.
