The JBO Thread Ring Gauge (NoGo) - Metric Fine, Right Hand, 4h, M12 x 0.5 is a precision external-thread gauge designed for fast, reliable inspection of thread diameters. It serves engineers, machinists, quality controllers, and maintenance teams who need to verify parts meet specified thread standards without guesswork. Made from hardened steel, this gauge combines durable construction with precise dimensions to maintain accuracy in demanding workshop environments and to clearly highlight non-conforming components.

• Durable hardened steel construction: Built to withstand daily wear in workshop and shop environments, maintaining accuracy and prolonging tool life.
• NoGo quick-check for non-conforming threads: Lets inspectors quickly identify parts that fail to meet spec, reducing rework and bottlenecks in production.
• Metric fine compatibility for M12 x 0.5: Precisely calibrated for metric fine threads with right-hand orientation, delivering consistent measurements across batches and setups.

By using this gauge, your quality checks become faster, more repeatable, and easier to document. The robust build resists wear over time, while the clear NoGo indication speeds decisions on acceptance or rejection, helping you maintain first-pass yields and traceable quality across your manufacturing or maintenance processes.
