JBO Thread Ring Gauge (GO) - Metric Fine - Right Hand - 4h - M13 x 0.5

The JBO Thread Ring Gauge (GO) is a precision Go gauge designed for metric fine external threads. It’s tuned for M13 x 0.5 with a 4h tolerance and right-hand thread, helping you quickly verify that threaded components meet the required size and class standard during production and inspection.

Machined from hardened steel, this gauge resists wear in demanding workshops and maintains measurement accuracy over many uses. Its straightforward design lets engineers, machinists, QA staff, and technicians identify conforming parts at a glance, keeping workflows moving.

• Precise Go gauge for Metric Fine Threads (M13 x 0.5, 4h): Enables fast acceptance testing of external threads—if the part threads onto the gauge cleanly, it conforms to the size and tolerance; streamlines quality checks and reduces rework.
• Hardened steel construction for durability: Built to withstand repeated use in busy workshops; resists wear and corrosion, helping maintain precise measurements over time.
• Right-hand orientation for quick, confident checks: Clear GO dimension is easy to read from standard viewing angles, simplifying setup and reducing operator errors during inspection.

With the JBO Thread Ring Gauge (GO), you gain a reliable, fast-quality checkpoint for external threads. It smooths the inspection process, supports consistent dimensional accuracy across parts, and helps your team meet standards with fewer delays. The hardened steel body delivers long service life in demanding environments, while the easy-to-use GO geometry helps inspectors and machinists quickly identify compliant components, improving overall throughput and product quality.
