The JBO Thread Ring Gauge (GO) – Metric Coarse, Right Hand, 4h, M3.5 x 0.6 is a precision tool designed to verify external metric coarse threads. It’s ideal for quality control teams, machinists, inspectors, and anyone who needs to confirm that threaded components will mate correctly with mating parts and fasteners.

Crafted from hardened steel for exceptional durability, this GO gauge delivers repeatable, trustworthy readings even in busy workshop environments. Its right-hand orientation and tightly controlled dimensions ensure accurate measurements of M3.5 x 0.6 threads and conform to the 4h tolerance class, helping you maintain consistent standards across projects.

• Precise GO gauge for metric coarse threads: Ensures accurate external thread diameter checks, enabling reliable pass/fail decisions for M3.5 x 0.6 components and reducing rework in QC processes.
• Hardened steel construction for durability: Built to resist wear in busy shops, delivering long-term accuracy and reducing replacement costs.
• Right-hand orientation and user-friendly design: Makes setup intuitive and readings quick and consistent, improving workflow in standard inspection routines.

Using this gauge as part of your QC workflow helps you quickly confirm that external threads meet the specified size and class, speeds up inspections, and reduces scrap by catching out-of-tolerance parts before they progress to assembly.
