The JBO Thread Plug Gauge is a precision Go/No-Go tool designed for metric fine-thread inspection. It’s ideal for engineers, machinists, quality inspectors, and technicians who need fast, reliable verification of threaded holes. This right-hand gauge is specified for M26 x 0.75 threads with a 6H tolerance, providing clear go/no-go feedback to keep assemblies aligned and consistent.

Constructed from hardened steel, this plug gauge delivers long-lasting wear resistance in busy workshop environments. The Go/No-Go design lets you quickly confirm both the tolerance and fit of internal threads, helping to minimize guesswork and rework during setup or in-process inspection.

• Go/No-Go quick verification: Enables fast pass/fail checks of internal threads, reducing inspection time and ensuring consistent hole quality.
• Metric fine-thread coverage (M26 x 0.75): Precisely targets the specified thread size, supporting accurate, repeatable inspections for right-hand threads.
• Durable hardened steel construction: Built to withstand daily use, delivering reliable performance and long service life in demanding environments.

Using the JBO Thread Plug Gauge helps streamline quality control, speed up setup and assembly, and deliver reliable threading results across parts—boosting overall workflow efficiency and confidence in every threaded connection.
