The JBO Thread Plug Gauge is a precision tool designed for metric coarse thread applications. It provides a Go/No-Go design that quickly confirms whether a threaded hole will accept or reject a component, supporting fast, accurate quality checks for M12 x 1.75 holes that follow the right-hand 6G standard.

Crafted from hardened steel, this gauge is built to withstand rugged use in workshops, job sites, and production lines, delivering long-lasting performance and dependable readings even after repeated insertions.

• Fast Go/No-Go inspection: Quickly confirm whether the threaded hole accepts a mating part or is out of tolerance, speeding up QC and reducing rework.
• Durable hardened steel construction: Built to withstand repeated use, resist wear, and maintain measurement accuracy over time in demanding environments.
• Metric coarse thread compatibility (M12 x 1.75, Right Hand 6G): Precisely matched to standard metric coarse threads, ensuring reliable fit with components and consistent results across assemblies.

With the JBO Thread Plug Gauge, you can expect faster, more reliable inspections, less downtime, and consistent results when servicing or manufacturing threaded parts. Its hardened steel build and precise metric coarse sizing ensure durable performance and accurate go/no-go judgments, empowering you to improve workflow, cut rework, and uphold quality across every project.
