The JBO Thread Plug Gauge is a precision inspection tool designed for metric fine threads, specifically sized for M10 x 0.75 with a 4H tolerance. Its Go/No-Go design provides quick, decisive hole checks, helping you confirm fit and avoid costly misfits during assembly.

Right-hand configuration and hardened steel construction deliver durable, repeatable readings in busy workshops, from production lines to maintenance bays.

• Go/No-Go design for fast validation: Quickly confirms whether a hole meets the size and tolerance, speeding up inspections and reducing rework.
• Hardened steel construction: Built to withstand daily use, resisting wear to maintain accuracy over thousands of checks.
• M10 x 0.75, 4H, right-hand specification: Precisely matched to common metric fine-thread holes, delivering consistent, trustworthy readings across parts and assemblies.

Used in quality control and assembly workflows, this gauge helps you verify threaded holes quickly, improve throughput, and reduce downtime. Its robust build and precise sizing give you confidence that your components will mate correctly, every time.
