The JBO Thread Plug Gauge is a precision tool designed for metric fine thread inspection. It helps engineers, machinists, and quality teams verify threaded holes quickly and accurately for reliable assembly with M16 x 1 components.

With a Go/No-Go design and right-hand orientation, this gauge supports fast, repeatable checks in busy shops. Its hardened steel construction delivers long-lasting wear resistance in demanding environments.

• Go/No-Go Quick Verification: The Go/No-Go design lets you quickly confirm thread acceptance and identify out-of-tolerance holes in seconds, streamlining setup and inspection.
• Durable Hardened Steel Construction: Built to endure daily shop use, offering excellent wear resistance and long service life in demanding environments.
• Right-Hand Metric Fine Thread Compatibility (M16 x 1, 4H): Precisely calibrated for M16 x 1 fine threads with a right-hand orientation and 4H class considerations, ensuring consistent seating and reliable checks across parts.

Using the JBO Thread Plug Gauge helps you confirm tolerances early, reduce rework, and speed up production QC, resulting in consistent fits and improved overall workflow.
