The JBO Thread Plug Gauge (NoGo) - Metric Fine, Right Hand, 6G, M45 x 2 is a precision tool designed to verify metric fine threaded holes. It’s ideal for engineers, machinists, inspectors, and maintenance teams who need quick, repeatable checks to ensure holes meet the upper limit of the specification for M45 x 2 threads in 6G class.

Manufactured with a hardened steel construction and a knurled, easy-grip body, this plug gauge delivers durability and reliable performance in busy workshops. The NoGo design supports fast, consistent size checks, helping you identify out-of-tolerance holes at a glance.

• NoGo verification for metric fine threads: Quickly confirm holes do not exceed the maximum allowable size for M45 x 2 threads in 6G, delivering consistent pass/fail results during routine quality checks.
• Durable hardened steel construction: Built to resist wear and maintain precise dimensions over time, ensuring reliable performance in daily inspection tasks.
• Ergonomic knurled grip for easy handling: The textured body provides a secure, comfortable grip—even with gloves—so you can position the gauge quickly and precisely in tight holes.

Using this gauge streamlines hole inspection, reduces guesswork, and helps maintain consistent thread quality across parts. It supports faster quality control, minimizes downtime due to rework, and gives you the confidence that threaded assemblies meet spec every time.
