JBO Thread Plug Gauge is a Go/No-Go plug gauge designed for metric fine threads, tailored for M29 x 0.75 with a 6H tolerance class. The right-hand configuration makes it compatible with standard threading checks in a wide range of precision components.

Ideal for machine shops, contract manufacturers, and quality teams, it provides a quick, reliable way to confirm that threaded holes will accept mating parts and fasteners as intended.

• Go/No-Go verification for fast QC: Quickly determine whether a threaded hole passes or fails to specification, reducing inspection time and guesswork on the shop floor.
• Metric fine thread specificity (M29 x 0.75): Precisely suited for fine-thread components, delivering consistent checks that support tight tolerance control.
• Durable hardened steel construction: Built to withstand daily wear, offering long-lasting performance and reliable repeatable results across many inspection cycles.

With this gauge, you gain time-saving, reliable checks that help keep production flowing. It supports accurate part fit, reduces misassembly, and maintains tight threading tolerances across batches, while its sturdy construction stands up to daily use in workshops and QC environments.
