The JBO Thread Plug Gauge is a precision inspection tool designed for internal metric fine threads. It’s ideal for engineers, machinists, inspectors, and assembly technicians who need to confirm hole readiness to the M32 x 1.5 specification with a 6G tolerance.

Crafted for durability, the gauge features a hardened steel body and a knurled grip that provides secure handling in busy workshops. The Go/No-Go design enables fast, clear pass/fail checks, helping you keep production moving.

• Go/No-Go for metric fine threads (M32 x 1.5, 6G): Quickly verify whether a threaded hole meets the exact spec, reducing inspection time and preventing mismatches in assemblies.
• Hardened steel construction: Built to resist wear from repeated use, preserving accuracy and extending service life in demanding workshop environments.
• Ergonomic knurled body with right-hand orientation: Delivers a secure grip and intuitive use in tight spaces, even when wearing gloves, for faster, more confident checks.

With the JBO Thread Plug Gauge, you gain reliable, repeatable measurements that streamline setup and quality checks. Its robust construction and precise Go/No-Go functionality help improve workflow, reduce rework, and ensure consistent mating of components across production runs.
