Designed for metric fine threads, the JBO Thread Plug Gauge lets you quickly verify hole sizes and thread quality. It's suitable for engineers, machinists, mechanics, and hobbyists who need reliable thread acceptance checks on M22 x 1.25 holes.

With a Go/No-Go design, right-hand orientation, and 6H tolerance, this hardened-steel gauge ensures consistent results across production runs and service checks, reducing guesswork and rework.

• Go/No-Go quick verification: Instantly confirm whether the M22 x 1.25 thread hole meets tolerance, speeding up inspections and eliminating guesswork.
• Hardened steel construction: Built to withstand daily use in workshops and production environments, delivering long-lasting durability and wear resistance.
• Metric fine-thread accuracy (M22 x 1.25, 6H): Precisely sized to ensure reliable, repeatable fits across parts and assemblies.

Using the JBO Thread Plug Gauge in your workflow helps you verify readiness in seconds, reduce rework, and keep assemblies moving smoothly from first-off checks to final inspection. The robust construction and precise sizing give you confidence in every measurement, whether you’re on a high-volume line or a precision-focused job.
