The Asimeto 686 Series Ring Thread Gauge (NoGo) in metric is a precision verification tool for right-hand M55 x 3 threads, designed to meet the strict 6g tolerance class. Ideal for quality control teams and machinists, it provides a clear, reliable pass/fail check to confirm your fasteners fit within specification.

• Series & Standards: 686 Series gauge designed for precise pitch-diameter measurement in metric threads, aligned with the 6g tolerance class.
• Thread Type: Right-hand metric thread gauge for M55 x 3 profiles, suitable for common high-strength fasteners.
• NoGo Designation: Used to determine if the thread pitch diameter is too large; if the fastener cannot pass through, it exceeds the maximum allowable limit.
• Accuracy & Durability: Crafted with high-quality materials to deliver durable, long-lasting performance in demanding workshop environments.
• Construction Details: Knurled exterior for secure handling and precise alignment during measurement.

This NoGo gauge delivers a definitive measurement approach: when a fastener fails to pass through the ring, inspectors know the thread pitch diameter is out of tolerance and must be rejected or redirected for rework. By providing a straightforward pass/fail result, it supports efficient quality control, reduces rework, and helps ensure that only properly sized fasteners enter critical assemblies. Whether used on a production line or in a repair shop, this gauge helps maintain consistent thread quality and reliable connections.
