The JBO Thread Plug Gauge is a precision Go/No-Go tool crafted for metric fine threads. Sized for M30 x 2 with a 6H tolerance and designed in a Right Hand orientation, it helps technicians quickly verify threaded holes and ensure proper mating with components.

With its straightforward Go/No-Go design, you get fast, unambiguous checks for hole threads, reducing guesswork and rework during assembly and inspection. The gauge is built from hardened steel, delivering long-lasting performance and wear resistance in busy workshop and production environments.

• Go/No-Go Verification: Quickly determine if the M30 x 2, 6H thread hole meets tolerance with clear pass/fail results, speeding up quality checks.
• Hardened Steel Construction: Built for durable, repeatable use in demanding shop settings, resisting wear over time.
• Right-Hand, Metric Fine Thread Compatibility: Precisely matched to fine-thread holes, delivering reliable checks for accurate assemblies.

Using the JBO Thread Plug Gauge helps streamline quality control and assembly workflows. It enables confident decisions at a glance, minimizes downtime from incorrect threading, and maintains measurement accuracy across repeated inspections.
