The JBO Thread Ring Gauge (NoGo) is a precision tool used to verify external metric-thread diameters, specifically tuned for fine-pitch threads. Designed for inspectors, machinists, engineers, and quality teams, it provides a clear pass/fail indication for M7 x 0.75 threads. With right-hand orientation and a 4h tolerance, this gauge delivers reliable NoGo checks that help you quickly confirm parts meet the required specifications.

• Knurled grip for easy handling: The textured outer edge lets you position the gauge confidently and quickly, even when wearing gloves, reducing setup time and improving measurement consistency.
• Hardened steel construction for durability: Built to withstand daily use in busy workshops, offering wear resistance that helps maintain stable measurements and longer tool life.
• Metric Fine, M7 x 0.75, Right Hand, 4h no-go profile: Precisely machined to the NoGo specification so you can identify non-conforming parts fast, supporting consistent quality control and efficient inspections.

Together, these features enable faster, more reliable inspections, reduce rework, and strengthen confidence in part quality across your manufacturing or assembly workflow. The gauge integrates smoothly into standard QC processes, helping teams make accurate decisions quickly and maintain tight tolerances on critical thread components.
