The JBO Thread Plug Gauge (NoGo) - Metric Fine - Right Hand - 6H - M125 x 4 is a precision inspection tool designed for metric fine threaded holes. It’s built for engineers, machinists, inspectors, and fabricators who need fast, reliable verification of hole size and thread fit during manufacturing, quality control, and assembly tasks.

• Metric Fine precision for reliable hole verification: Designed to the M125 x 4 fine-thread specification with a 6H tolerance, enabling consistent NoGo checks that help confirm holes meet exact standards without guesswork.
• Hardened steel construction for durability: Crafted from high-quality hardened steel with a wear-resistant finish, delivering long-lasting performance in demanding workshop environments.
• Right Hand design for streamlined inspection workflows: The right-hand orientation supports standard inspection procedures, allowing quick setup and repeatable, confidence-inspiring results.

Used as a go/no-go reference, this metric fine NoGo gauge helps reduce rework and ensure threaded holes accept components within spec, improving workflow efficiency and overall quality across production or repair environments.
