The JBO Thread Plug Gauge is a precision Go/No-Go tool designed for fast, reliable inspection of metric fine-threaded holes. It’s ideal for machinists, inspectors, and assembly teams working with M36 x 1.5 right-hand threads, delivering quick pass/fail results to verify thread quality.

Built for daily use, this gauge features hardened steel construction that resists wear and maintains accuracy over time, even in demanding workshop environments.

• Go/No-Go Quick Checks: Fast pass/fail verification of hole threads, reducing inspection time and guesswork.
• Hardened Steel Durability: Rugged, wear-resistant body that stands up to daily use and long service life.
• Metric Fine Thread Specific (M36 x 1.5) with Right-Hand Orientation: Tested for the exact size and thread direction used in your parts, delivering consistent, repeatable results.

Using this gauge streamlines quality checks, cuts downtime, and helps ensure every part threads correctly the first time. The combination of quick Go/No-Go checks, durable construction, and precise metric fine-thread compatibility translates to faster setup, fewer reworks, and more reliable assemblies across production runs.
