The JBO Thread Plug Gauge is a precision tool designed for metric coarse threads. Sized for M5 x 0.8 with right-hand orientation and 4H tolerance, it uses a go/no-go design to quickly verify threaded holes and ensure proper fitment of components in manufacturing and assembly tasks.

• Go/No-Go quick checks: The two-end design lets you rapidly confirm whether a threaded hole meets the M5 x 0.8 specification, speeding inspections and reducing guesswork.
• Hardened steel construction: Built to withstand daily use in busy workshops, resisting wear and maintaining accuracy over many testing cycles.
• Metric coarse-thread design (M5 x 0.8): Specifically engineered for common coarse-thread sizes, ensuring reliable checks and compatibility with standard components.

With this gauge, you can streamline quality control, cut inspection time, and improve consistency across parts. The durable construction gives you confidence in long-term reliability, helping you minimize downtime and deliver accurate, repeatable results on every job.
