The JBO Thread Ring Gauge (NoGo) - Metric Fine, Right Hand, M17 x 1, 6g is a precision external thread gauge designed to verify metric fine-thread components with speed and accuracy. It’s an essential tool for engineers, machinists, quality inspectors, and maintenance teams who need reliable go/no-go checks to confirm thread dimensions meet exact standards.

Manufactured from hardened steel for lasting durability, this NoGo gauge stands up to daily use in busy workshops while maintaining stable accuracy over many inspections. Its user-friendly design makes it straightforward to identify non-conforming threads during routine quality control, helping you keep production moving smoothly.

• Fast, reliable NoGo verification: Quickly confirm non-conforming external threads by preventing full engagement, speeding QC and reducing misreads.
• Metric fine thread fit: M17 x 1, right-hand: Precisely matches the target size and thread form used in many applications, ensuring accurate go/no-go results every time.
• Durable hardened steel with knurled edge: Built to withstand daily shop use, offering long life and easy handling during inspections.

Using this gauge helps streamline your workflow by delivering clear, actionable feedback on thread compliance. The NoGo design reduces guesswork, minimizes downtime, and supports consistent thread quality across batches. With hardened steel construction and precise metric sizing, you can rely on accurate results, lower scrap rates, and faster throughput in production, maintenance, or quality control environments.
