The JBO Thread Plug Gauge (GO) is a metric fine-thread go gauge designed for assessing threaded holes with precision. Suited for engineers, machinists, quality inspectors, and workshop teams, it validates that M50 x 1.5, right-hand threads meet the 6H tolerance in a quick, go/no-go check. Crafted to support reliable inspection across manufacturing and assembly environments, this gauge helps ensure components fit correctly from the first part to final assembly.

• Precise GO size for Metric Fine M50 x 1.5: Quickly confirm threaded holes conform to the M50 x 1.5 specification, with correct right‑hand orientation and 6H tolerance, delivering clear pass/fail results during quality checks.
• Hardened steel construction for long life: Built to resist wear from frequent use, maintaining accurate dimensions and delivering durable performance in demanding shop conditions.
• Ergonomic knurled grip and intuitive use: Easy handling and insertion reduce setup time and operator fatigue, enabling faster inspections and consistent results.

Designed for dependable, repeatable thread verification, the JBO GO gauge helps you streamline quality control, cut down rework, and keep your production workflow moving smoothly—from initial setup through final assembly.
