The JBO Thread Plug Gauge (NoGo) - Metric Fine - Right Hand - 4H - M55 x 1.5 is a precision measuring tool designed to verify threaded holes with metric fine threads. It helps quality teams, machine shops, and assembly lines confirm hole size and tolerance quickly and accurately.

Made from hardened steel and built to resist wear, this gauge delivers long-lasting performance in demanding environments, maintaining accuracy over many inspections.

• NoGo gauge for Metric Fine threads (M55 x 1.5): Specifically calibrated for metric fine thread sizes, this NoGo plug gauge provides a fast, clear check to verify hole size against the M55 x 1.5 specification and 4H tolerance, helping you identify out-of-tolerance components before assembly.
• Hardened steel construction: Built to withstand frequent use, this gauge resists wear and maintains precise dimensions for reliable, repeatable measurements over time.
• Right hand orientation: Designed to match standard right-hand thread conventions, ensuring intuitive use and quick setup in common inspection workflows.

Using the JBO Metric Fine NoGo gauge simplifies and speeds up hole inspection, reduces rework, and supports consistent quality across parts. Its robust build and precise calibration mean you can rely on accurate pass/fail results, improve throughput in QA and assembly, and make confident manufacturing decisions.
