The JBO Thread Ring Gauge (NoGo) is a precision tool used to check external threads on components and fasteners. Designed for manufacturers, machine shops, and quality teams, it helps you quickly confirm whether a part’s thread diameter is within spec.

Configured for metric fine threads (M12 x 0.5) in the 6e class and right-hand orientation, this gauge provides a reliable, durable way to identify out-of-tolerance parts during routine inspections and final assembly.

• Precise NoGo Check for M12 x 0.5 Fine Threads (6e): Quickly confirms external thread diameters are within tolerance, speeding up in-process inspections and reducing the risk of fitting undersized or oversized fasteners.
• Hardened Steel Construction for Long Life: Built to resist wear in busy workshops, maintaining dimensional accuracy through thousands of inspections.
• Metric Fine M12 x 0.5 Right-Hand Alignment: Specifically tailored for common right-hand, metric-fine threads, ensuring consistent and repeatable checks across parts.

Using this gauge helps streamline quality control, reduce inspection time, and improve confidence in thread integrity across production runs. Its robust build and precise sizing help minimize downtime, avoid costly rejects, and ensure smooth, dependable assembly and maintenance outcomes.
