The JBO Thread Plug Gauge is a precision inspection tool designed for metric fine threads. Specifically engineered for right-hand M23 x 0.75 threads with a 6H tolerance, it enables quick Go/No-Go checks to verify threaded holes and ensure perfect mating with corresponding parts. Ideal for machine shops, automotive, aerospace, and maintenance teams, it helps quality checks happen fast without guesswork.

Made from hardened steel for lasting performance, this gauge resists wear through repeated use in busy environments. Its knurled body provides a secure grip and easy handling in tight spaces, so you can perform precise checks confidently, even on crowded workbenches.

• Go/No-Go Quick Verification: Quickly confirm whether a hole falls within tolerance, speeding up inspections and reducing rework.
• Hardened Steel Durability: Built to endure frequent use with excellent wear resistance, delivering reliable accuracy over time.
• Metric Fine Precision (M23 x 0.75, 6H, Right Hand): Specifically sized for fine metric threads, ensuring correct fit and consistent results across batches.

Using this gauge streamlines assembly and maintenance workflows by delivering clear pass/fail results, minimizing downtime, and providing confidence in every threaded connection you inspect.
