The JBO Thread Plug Gauge is a precision Go/No-Go tool tailored for metric fine threads, designed to streamline hole inspection in assemblies and quality checks. With a right-hand configuration and M5 x 0.75 sizing within a 6H tolerance, it’s a practical choice for engineers, machinists, and shop floor teams seeking quick, reliable verification of threaded holes.

Crafted from hardened steel, this gauge delivers lasting performance in busy workshops. The knurled grip provides a secure, comfortable hold for accurate handling, even in tight spaces, while the durable body stands up to daily use and repeated checks.

• Go/No-Go quick inspection: Quickly determine hole tolerance—if the Go end fits and the No-Go end doesn’t, the thread is within spec, saving time and reducing guesswork.
• Hardened steel construction: Built to resist wear and corrosion, ensuring long service life and consistently accurate measurements for busy environments.
• Metric Fine-Thread Calibration (M5 x 0.75, 6H, Right-Hand): Precisely tailored for common metric fine threads, delivering dependable checks for correct hole size and fit on M5 x 0.75 right-hand threads.

Used in production or maintenance settings, this gauge helps you verify threaded holes quickly, cut down setup time, and prevent assembly issues caused by out-of-tolerance threads. Its robust build and precise calibration give you confidence in every measurement, supporting efficient workflows and consistent, high-quality results across projects.
