Description
The JBO Thread Plug Gauge is a precision tool for inspecting metric coarse threads in threaded holes. Designed for engineers, machinists, quality control teams, and maintenance professionals, it speeds up acceptance testing with a simple go/no-go check that confirms holes are ready for assembly.
Specifically configured for right‑hand M9 x 1.25 coarse threads and 6H tolerance, this gauge is built from hardened steel for enduring performance in demanding shop environments, delivering reliable, repeatable results every time.
- Fast Go/No-Go verification: The go/no-go design lets you quickly confirm whether a threaded hole passes or fails in a single check, reducing inspection time and rework and supporting consistent assembly across batches.
- Designed for metric coarse threads (M9 x 1.25): Precisely matched to M9 x 1.25 coarse threads, ensuring accurate hole evaluation for common components and fasteners used in everyday manufacturing and maintenance work.
- Hardened steel construction with reliable durability: Hardened steel resists wear from repeated insertions, providing long-lasting accuracy in busy workshops. A knurled body helps secure grip for precise handling.
Using this plug gauge helps you verify hole readiness in seconds, speeding up quality control, reducing the risk of mismatched assemblies, and delivering consistent results across projects. Its rugged construction minimizes replacement needs, giving your team confidence to rely on accurate thread checks day after day.
