The JBO Thread Plug Gauge is a precision inspection tool designed for metric fine threads, providing fast, reliable checks that help ensure threaded holes will fit mating fasteners perfectly. Ideal for engineers, machinists, quality teams, and workshop specialists, this Right Hand gauge is calibrated for M26 x 1.5 fine threads to support tight tolerance work and consistent results across production runs.

• Go/No-Go quick validation: Enables fast pass/fail checks of hole threads in seconds, reducing inspection time and preventing misfits in assembly.
• Precise M26 x 1.5 fine-thread fit: Specifically tuned for metric fine threads with 6G tolerance, ensuring consistent, repeatable results when validating threaded holes.
• Hardened steel construction: Durable, wear‑resistant material that stands up to daily use in demanding shop environments while maintaining long-term accuracy.

Using this gauge streamlines your inspection workflow, minimizes downtime, and improves upfront quality for threaded assemblies. The Go/No-Go design delivers immediate, actionable feedback, helping you quickly confirm part suitability and reduce rework, so production stays on schedule and results stay reliable.
