The JBO Thread Ring Gauge (NoGo) for Metric Fine threads is a precision inspection tool designed to verify external thread diameters with reliability and ease. Crafted for engineers, quality teams, machinists, and workshop technicians, it helps confirm that fasteners and threaded components meet the required NoGo limits and stay within tight metric tolerances at M100 x 1.5, right-hand orientation.

• NoGo Quick-Check for Compliance: Quickly determine if external threads fail the NoGo limit, enabling fast identification of out-of-tolerance parts during quality inspections and reducing rework.
• Durable Hardened Steel Construction: Built to withstand daily use in busy workshops, delivering long-lasting performance and maintaining measurement accuracy even in demanding environments.
• Metric Fine Precision: M100 x 1.5 Right-Hand: Precisely calibrated for metric fine threads, providing consistent, reliable checks that align with standard fasteners and threaded components.

Together, these features streamline inspection workflows, improve accuracy across batches, and build confidence in every measurement. The JBO NoGo gauge delivers dependable performance for precision engineering, quality control, and efficient manufacturing processes.
