The JBO Thread Plug Gauge is a precision tool designed for verifying metric fine threads in internal holes. Sized for M9 x 0.75 with a right-hand thread and 6G class, this Go/No-Go gauge provides quick, reliable checks to confirm that threaded holes will accept mating parts as intended. It's ideal for machine shops, manufacturers, and quality control teams looking to prevent fit issues before assembly.

• Fast Go/No-Go Verification: Quickly determine acceptance or rejection of a hole’s threads—go indicates proper fit, no-go shows an out-of-tolerance condition—helping you move from inspection to assembly with confidence.
• Rugged Hardened Steel Build: Engineered for daily shop use, the hardened steel resists wear and maintains accuracy through repeated measurements, reducing replacement costs and downtime.
• Precise Metric Fine-Thread Check (M9 x 0.75, 6G, Right-Hand): Specifically matched to metric fine-thread standards, delivering consistent results across parts and suppliers and simplifying quality control workflows.

Using this gauge streamlines your testing process, minimizes rework, and supports reliable assemblies. The durable construction and precise sizing help you achieve consistent, repeatable results across production runs, giving you clear pass/fail indications and greater overall workflow efficiency.
