The JBO Thread Ring Gauge (NoGo) is a precision inspection tool for external metric fine threads. Designed for engineers, machinists, quality inspectors, and buyers, this NoGo gauge lets you quickly verify that M25 x 1 threads meet the required size and tolerance.

Made from hardened steel for durability, the gauge resists wear in busy workshops and maintains accurate measurements through heavy use. The NoGo design provides a clear, quick pass/fail for non-conforming parts, helping you maintain consistent quality across production runs.

• Efficient go/no-go verification: Quickly confirm external thread size against standard, enabling fast, reliable inspections and reducing guesswork.
• Durable hardened steel construction: Built to withstand daily use in demanding environments, preserving accuracy and extending gauge life.
• Precise metric fine specification (M25 x 1, 6g, Right Hand): Tests the exact thread form you work with, supporting consistent results and fewer reworks.

Using the JBO Thread Ring Gauge helps streamline quality control by delivering fast, dependable feedback on thread accuracy. Its robust construction minimizes downtime due to worn tools, while the clear Go/NoGo indication supports efficient decision making, improving workflow, compliance, and overall production performance.
