The JBO Thread Ring Gauge (NoGo) for Metric Coarse threads is a precision inspection tool designed to verify external threads on fasteners and components. Ideal for quality control teams, machine shops, and assembly lines, it helps confirm that M18 x 2.5 right-hand threads meet the NoGo limit and stay within the 4h tolerance.

Crafted from hardened steel, this gauge delivers durable, long-lasting performance in demanding environments. The straightforward NoGo check makes it easy for operators to spot non-conforming parts at a glance, helping reduce rework and ensure consistent mating with female threads across production runs.

• NoGo verification for metric coarse threads: Quickly identify external threads that fail the NoGo limit, speeding up inspections and preventing incorrect components from progressing in the line.
• Hardened steel construction for durability: Designed to withstand daily use and wear, preserving accuracy and extending the life of the gauge in busy workshops.
• 4h tolerance for M18 x 2.5 right-hand threads: Precisely aligned with standard metric coarse-thread specs to deliver repeatable, reliable checks across parts and batches.

Using the JBO NoGo Ring Gauge helps streamline quality control, improve workflow consistency, and ensure that external threads meet essential standards for reliable fits and proper function in every assembly.
