The JBO Thread Plug Gauge (NoGo) - Metric Fine - Right Hand - 6H - M90 x 6 is a precision measuring tool designed for metric fine threads. It’s ideal for engineers, machinists, inspectors, and shop-floor QA teams who need a quick, reliable way to verify threaded holes meet the M90 x 6 standard with 6H tolerance, ensuring proper fit and consistent quality.

• Exact Metric Fine NoGo sizing (M90 x 6): Quickly confirms threaded holes do not exceed the maximum size, helping you identify oversize holes and ensure reliable engagement with corresponding fasteners.
• Right-Hand orientation for standard use: Optimized for common right-hand thread configurations, delivering consistent test results across a wide range of components and assemblies.
• Durable hardened steel construction with knurled grip: Built to withstand demanding workshop use, with wear resistance and a textured grip for secure, repeatable measurements over time.

Using the gauge simplifies quality control by providing fast, go/no-go verification that threaded holes are within spec. Its precise dimensions and rugged build support accurate inspections in busy environments, helping you reduce rework, improve part compatibility, and maintain consistent performance across production runs.
