The JBO Thread Ring Gauge (GO) – Metric Coarse, Right Hand, 6H, M1 x 0.25 is a precision go gauge designed to verify external metric threads quickly and reliably. It’s ideal for quality control teams, machinists, engineers, and hobbyists who need to confirm that a part will screw into its mating component with the correct thread form and size.

Constructed from hardened steel for lasting durability, this gauge maintains accuracy even in busy workshop environments. Its simple, robust design supports fast inspections, helping you validate thread fitment with confidence and reduce rework.

• Precise GO gauge for metric coarse threads: Quickly confirm correct thread engagement for M1 x 0.25 coarse threads with right-hand orientation through a straightforward go/no-go check, speeding up inspections and ensuring proper fit.
• Durable hardened steel construction: Built to resist wear and keep its accuracy over many cycles, delivering a long service life in demanding shop conditions.
• Defined size and orientation for consistent results: With its right-hand thread and 6H tolerance specification, it provides a reliable reference that reduces guesswork and standardizes quality checks across parts and batches.

Used correctly, this gauge streamlines your inspection workflow, helps you meet tighter tolerances, and supports consistent mating with metric coarse threaded components. It’s a dependable tool that contributes to faster quality assurance, fewer defects, and greater confidence in every threaded assembly.
