The JBO Thread Ring Gauge (NoGo) for metric fine threads is a right-hand gauge engineered to confirm external thread diameters with precision. It’s tailored for applications demanding strict conformance to metric fine thread standards, such as M14 x 1 with a 6h tolerance, making it a dependable tool for engineers, machinists, quality inspectors, and maintenance teams.

• Fast NoGo verification for quick inspections: clearly indicates non-conforming threads, enabling rapid go/no-go decisions and reducing inspection time.
• Hardened steel construction for durability: built to withstand daily use in demanding environments, delivering long-lasting performance and wear resistance.
• Specifically tuned for M14 x 1 right-hand threads (6h): ensures accurate, repeatable measurements that align with standard specifications and improve inspection consistency.

Using this gauge helps streamline quality control, reduce rework, and maintain consistent thread quality across parts and batches. Its robust construction and clear indication support reliable decisions, boosting overall workflow efficiency and confidence in every threaded assembly you deliver.
