The JBO Thread Plug Gauge is a precision inspection tool designed for metric fine threads, ideal for applications where precise threading matters. Built for right-hand M11 x 1 holes in the 6H class, its Go/No-Go design lets you quickly verify thread acceptance and ensure components fit together smoothly.

• Go/No-Go metric fine thread checks: Quickly determine if a hole accepts the full thread (Go) or should be rejected for being too tight (No-Go), delivering fast, repeatable pass/fail results and reducing inspection time.
• Hardened steel construction for durability: Designed to withstand daily use in busy workshops, providing long-lasting wear resistance and stable accuracy over many cycles.
• Ergonomic knurled handle for secure handling: The textured grip offers a confident, comfortable hold and precise control during insertion and removal, even in tight spaces.

With its Go/No-Go design and robust build, this gauge helps you verify thread readiness quickly, minimize rework, and maintain consistent results across parts that use M11 x 1 threads within the 6H tolerance class. It’s a reliable, easy-to-use tool that supports efficient quality control on any shop floor.
