The JBO Thread Plug Gauge is a precision tool for metric fine threads, designed to verify internal threads quickly and accurately. Specifically matched to M23 x 1 right-hand threads and 6G tolerance, it’s ideal for machinists, inspectors, and assembly teams that require consistent fit between threaded components.

Built for durability, the gauge uses hardened steel to withstand frequent use and resist wear over time. The knurled body provides a secure grip for precise handling during inspection, while the Go/No-Go design supports quick checks of threaded holes to confirm they meet the M23 x 1 right-hand thread specification.

• Go/No-Go design for fast, reliable hole checks: Quickly determine whether a threaded hole meets spec, reducing guesswork and rework during setup and assembly.
• Hardened steel construction for long-lasting durability: Built to endure daily use in busy workshop environments with consistent performance over time.
• Right Hand, 6G tolerance for precise M23 x 1 threads: Ensures repeatable, accurate checks that align with mating parts and standard manufacturing tolerances.

Using this gauge helps streamline quality control, shorten setup times, and deliver reliable results across production runs. It gives technicians a clear pass/fail indication, enhancing confidence in every threaded connection and helping maintain smooth workflow from machining to final assembly.
