The JBO Thread Plug Gauge is a precision tool engineered to verify metric fine-thread holes with precise Go/No-Go checks. It’s ideal for machinists, quality inspectors, assembly technicians, and engineers who need quick, reliable feedback during drilling, tapping, or assembly processes. Use it to confirm holes accept fasteners as intended, helping you reduce misfits and rework.

This Right Hand gauge covers M2 x 0.2 threads with a 4H tolerance, delivering dependable performance in everyday workshop workflows. Built from hardened steel, it resists wear to preserve accuracy even after repeated use in demanding environments.

• Go/No-Go design for fast, definitive hole checks: Quickly determine whether a threaded hole meets spec, speeding inspections and reducing guesswork in assembly lines.
• Hardened steel construction for long-lasting durability: Resists wear and maintains precise dimensions over time, ensuring consistent results across many inspections.
• Metric fine thread compatibility: M2 x 0.2, Right Hand, 4H: Ensures reliable fit checks for common metric taps and fasteners, supporting broad compatibility with standard parts.

Use this plug gauge to streamline quality control, shorten setup times, and improve overall thread-fit confidence across your projects.
