The JBO Thread Ring Gauge (NoGo) is a precision tool for quickly verifying external metric threads. Specifically designed for M30 x 0.75 right-hand, 6h class, metric-fine pitch, it helps inspectors and machinists confirm parts meet the NoGo limit and prevent misfits from passing inspection.

• Accurate M30 x 0.75 NoGo profile: Provides a quick, reliable check of external thread diameter to the M30 x 0.75 fine pitch, helping you catch non-conforming parts early and reduce rework.
• Hardened steel construction: Built to withstand frequent use in busy workshops; durable surfaces resist wear and retain precise dimensions over time.
• Ergonomic, user-friendly design: Knurled outer edge for secure grip; clear red alignment mark aids fast orientation; simple handling supports consistent inspections across operators.

Using the JBO NoGo gauge simplifies your quality control workflow. It enables fast, dependable checks, helping you approve compliant components on the first pass, minimize downtime, and maintain consistent thread quality across production runs.
