The JBO Thread Plug Gauge is a precision Go/No-Go tool designed for quick, reliable inspection of metric fine-threaded holes. It’s ideal for engineers, machinists, quality inspectors, and workshop teams who need fast, confident pass/fail checks on internal threads.

This gauge is calibrated for M14 x 0.75 right-hand threads with a 6H tolerance, delivering clear indication of acceptable and out-of-tolerance holes to keep your assemblies running smoothly.

• Go/No-Go inspection design: Quickly confirm whether a threaded hole meets the M14 x 0.75 6H specification, speeding up quality checks and reducing guesswork on the shop floor.
• Durable hardened steel construction: Built to withstand daily use, resisting wear and maintaining accuracy over many cycles in busy workshops.
• Right-hand metric fine thread compatibility: Precisely machined for the intended right-hand M14 x 0.75 threads, delivering consistent readings and minimizing rework from incorrect checks.

Using the JBO Thread Plug Gauge helps you streamline your quality workflow: faster, clearer inspections that reduce downtime and prevent mismatches in critical assemblies. Its robust construction and precise Go/No-Go action deliver dependable results, so you can trust every measurement and keep production moving with confidence.
