Description
JBO Thread Ring Gauge (NoGo) for Metric Coarse threads is a precision inspection tool built for engineers, technicians, and quality teams. Sized for right-hand M18 x 2.5 threads (6h), it uses strict NoGo limits to quickly verify external thread diameters meet the required standards, helping ensure proper fit and reliable performance in assemblies.
- NoGo quick conformity checks: Instantly reveals any oversized or undersized NoGo condition, speeding inspections and reducing rework time.
- Hardened steel construction: Durable, wear‑resistant material that stands up to daily use in busy workshops and harsh environments for long service life.
- Metric coarse compatibility (M18 x 2.5, right-hand, 6h): Specifically tuned for common metric coarse threads, ensuring reliable checks and easy integration into existing QC workflows.
Using the JBO Thread Ring Gauge (NoGo) helps streamline quality control, improve consistency across parts, and shorten the path from measurement to confident decision. The NoGo verification provides clear pass/fail indications, supporting accurate fitting, reducing downtime, and ensuring components meet accuracy standards in manufacturing, assembly, and maintenance programs.
