The JBO Thread Ring Gauge (NoGo) is a precision tool designed to quickly verify external metric threads in right-hand configurations. Tuned for M14 x 0.5 with a 6h specification, this NoGo gauge provides fast, reliable checks that confirm parts meet the required thread size and pitch.

Built from hardened steel, the gauge offers exceptional durability and wear resistance, making it suitable for daily use in manufacturing, machining, and quality control environments. Its simple, intuitive design helps technicians and inspectors identify non-conforming threads at a glance, supporting consistent, repeatable measurements across lots and shifts.

• Fast NoGo verification: Quickly determine if a threaded component is within specification by using the NoGo check, reducing inspection time and downstream rework.
• Rugged, wear-resistant hardened steel: Built to withstand daily use and resist wear in tough shop conditions, delivering long service life.
• Clear, consistent metric fine sizing: Precisely matched to M14 x 0.5 right-hand threads with 6h characteristics so checks are easy to interpret and repeat across operators.

This gauge helps streamline your inspection workflow by enabling rapid, confidence-backed pass/fail decisions on external threads. With durable construction and a precise NoGo limit, it reduces downtime, minimizes rework, and supports dependable, standards-compliant results across production runs. The compact, user-friendly design makes it accessible to engineers, quality inspectors, or shop-floor technicians, helping your team deliver consistent quality with every part.
