JBO Thread Plug Gauge (NoGo) for metric fine threads is a precision hand tool designed to verify internal threads in metric holes. Suitable for engineers, machinists, inspectors, and fabrication teams, it checks holes against the M145 x 1.5, 6H specification with a straightforward NoGo-style check, helping you confirm correct thread fit quickly and reliably.

• Metric Fine precision for M145 x 1.5, 6H: specifically engineered for metric fine threads to deliver accurate hole checks, helping you prevent mismatches and ensure parts assemble correctly.
• Hardened steel construction for durability: built to withstand daily use in demanding environments, resisting wear to maintain dimensional accuracy over time.
• Ergonomic knurled grip with a compact design: easy to handle and insert, enabling fast, repeatable inspections even in tight spaces.

With the JBO NoGo gauge, you gain faster setup, clearer pass/fail decisions, and consistent thread quality across production runs. Its durable build and thoughtful ergonomics help reduce downtime and increase confidence in every measurement.
