The JBO Thread Plug Gauge is a precision instrument designed for metric fine-thread inspection. It helps quality teams, machinists, and maintenance staff verify threaded holes quickly and with confidence, ensuring mating parts align perfectly. This Right Hand Go/No-Go gauge targets M23 x 1 threads with 6H tolerance; its hardened steel construction delivers durability for daily workshop use and long tool life.

• Go/No-Go quick checks: Quickly confirms whether a threaded hole is within tolerance, delivering clear pass/fail results and speeding up quality control.
• Metric fine thread accuracy: Engineered for M23 x 1 threads with 6H tolerance, ensuring consistent, repeatable checks across parts.
• Durable hardened steel construction: Built to withstand frequent use in busy workshops, resisting wear to maintain long-term accuracy.

With the JBO Thread Plug Gauge, you’ll speed up your inspection routine, reduce rework, and improve first-time fit across assemblies. The clear pass/fail checks minimize guesswork, while the rugged construction keeps precision reliable through daily use, helping you keep production moving and quality consistently high for components that rely on M23 x 1 threads.
