The JBO Thread Ring Gauge (GO) - Metric Fine - Right Hand - 6h - M20 x 2 is a precision inspection tool used to verify external thread diameters on fasteners and machined components. It’s ideal for engineers, quality control professionals, machinists, and workshop technicians who need fast, reliable go checks to confirm parts meet metric fine-thread standards.

Made from hardened steel for long-lasting durability, this GO gauge resists wear in busy production environments. The knurled outer edge provides a secure grip, while the right-hand, metric-fine thread profile (M20 x 2, 6h) helps deliver consistent, repeatable measurements during every inspection.

• Precise GO verification for metric fine threads: Quickly confirm external thread diameters against the M20 x 2, 6h standard, enabling fast pass/fail decisions and reducing inspection time.
• Durable hardened steel construction: Built to resist wear and maintain calibration, delivering long tool life in high-volume quality control applications.
• User-friendly, secure handling with knurled edge: Easy to grip and align, making repeated inspections quick and comfortable in busy workshops.

Using the gauge helps streamline quality control, reduce rework, and maintain consistent threaded fits across parts and assemblies. It speeds up inspections, minimizes downtime, and provides clear, reliable results you can trust for dependable assembly and performance in every project.
