The JBO Thread Plug Gauge is a precision Go/No-Go gauge designed for metric fine-thread holes. It’s tuned for M7 x 0.75 right-hand threads with a 6H tolerance, enabling fast, reliable checks during machining, assembly, and quality control.

With a dual-ended Go/No-Go design and a rugged, knurled body, this gauge lets you verify holes quickly in tight spaces, improving workflow and reducing guesswork in everyday production tasks.

• Dual-ended Go/No-Go design: Quickly confirm that a hole accepts the M7 x 0.75 right-hand thread and remains within tolerance, delivering fast, decisive results and reducing inspection time.
• Hardened steel construction: Built to resist wear and maintain accurate measurements through heavy daily use in busy workshops, ensuring long service life.
• Ergonomic knurled body: Provides secure, comfortable handling and precise control in confined spaces, increasing inspection accuracy and reducing hand fatigue.

Using the JBO Thread Plug Gauge streamlines threaded-hole inspection, delivering fast, decisive results that cut setup time and rework. By reliably confirming hole size and tolerance, it helps you avoid misfits, speed assembly, and maintain consistent quality across parts and batches, even in high-demand production environments.
