Precision metric NoGo ring gauge from the Asimeto 686 Series, designed for accurate verification of right-hand M40 x 3 threads. It confirms adherence to the 6g tolerance class, ensuring fasteners fit reliably in everyday manufacturing and maintenance tasks.

• Series: 686 Series NoGo ring gauge engineered for durable, repeatable use.
• Thread Specification: Right-hand metric thread M40 x 3 undergoing 6g tolerance checks.
• NOGO Designation: Clearly indicates out-of-tolerance conditions when a fastener cannot pass through the gauge.
• Measurement Focus: Validates thread pitch diameter to ensure proper fit, not just external dimensions.
• Material & Construction: Crafted from high-quality materials to withstand regular inspection cycles.
• Ideal For: Quality control labs, supplier inspections, and production-line verification in machining and assembly environments.
• Orientation: Optimized for right-hand threaded components common in standard fastener applications.

Using this gauge helps ensure that only correctly sized fasteners enter your assembly process, reducing the risk of binding, loosening, or improper joints. The NoGo feature provides a straightforward pass/fail result, supporting rapid frontline checks and consistent quality across batches. Its precision design makes it a reliable, long-lasting tool for engineers, inspectors, and maintenance teams working with metric thread standards.
