The JBO Thread Plug Gauge (NoGo) – Metric Fine, Right Hand, 6H, M110 x 4 is a precision inspection tool designed to verify metric fine threaded holes. It helps quality teams, machinists, inspectors, and hobbyists confidently confirm hole size and tolerance, ensuring components meet exact specifications without guesswork.

Built for demanding environments, this gauge features hardened steel construction and a textured knurled body for secure handling, delivering reliable, repeatable checks time after time.

• Precision for metric fine threads: Designed for metric fine threads (M110 x 4) and 6H tolerance to ensure accurate hole checks and consistent results.
• Durable hardened steel construction: Built to withstand daily use in inspection and manufacturing environments, resisting wear for long life.
• Ergonomic, quick NoGo checks: Right-hand gauge orientation with a knurled grip enables fast, repeatable go/no-go measurements with minimal setup.

The result is a faster, more reliable inspection process that helps you confirm threaded holes meet spec, reduce rework, and improve overall manufacturing quality. The JBO Metric Fine NoGo gauge supports consistent results across teams—whether in engineering, production, or maintenance—so you can trust your measurements and keep workflows moving smoothly.
