The Asimeto Ring Thread Gauge (NoGo) is a precision metric tool designed for machinists, quality teams, and maintenance professionals who need exact control over M39 x 1 threads. With a focus on reliability and clear pass/fail results, this NoGo gauge helps ensure every fastener meets the specified pitch diameter.

• Series: 686 Series Ring Gauges crafted for precision and durability.
• Thread size: Metric M39 x 1, right-hand threads, targeted to the 6g class.
• Tolerance: 6g tolerance class to ensure accurate pitch-diameter measurement.
• NoGo designation: Quickly confirms if a fastener’s thread pitch diameter is within tolerance; if it cannot pass through, it’s out of spec.
• Design & finish: Knurled outer edge for secure handling and consistent alignment during inspection.
• Materials & durability: Built with high-quality materials to withstand regular use in demanding workshop environments.
• Application: Ideal for quality control, machining shops, assembly lines, and maintenance teams needing reliable thread validation.

This NoGo gauge provides decisive, repeatable verification of thread size, helping prevent oversized fasteners from entering critical assemblies. By confirming that the pitch diameter stays within the maximum limit, it supports safe, reliable connections and reduces rework due to threading mismatches. Use as part of a structured thread inspection process to maintain consistent fit and finish across projects.
