Meet the JBO Thread Ring Gauge (NoGo) for metric fine threads — a precision tool for verifying external thread sizes. Designed for engineers, machinists, QA teams, and workshop technicians, it provides fast, reliable go/no-go checks on M25 x 2 right-hand threads with a 6h tolerance, helping ensure components meet exact specifications.

• Durable, wear-resistant construction: Hardened steel body and precision ring surface resist wear and maintain accuracy through heavy, everyday use in busy shops and production lines.
• Fast, reliable NoGo verification: Instantly reveals non-conforming threads, speeding up inspections, reducing rework, and improving overall batch quality.
• Metric fine thread compatibility (M25 x 2, 6h, Right-Hand): Precisely tuned for common metric fine threads with a right‑hand orientation, delivering consistent, repeatable measurements across operators.

Using this gauge streamlines your quality workflow by providing clear pass/fail signals, reducing inspection time per part, and helping your team consistently meet tight tolerances. Its rugged build and precise dimensions translate to long service life in demanding environments, delivering dependable performance and elevating overall product quality.
