Professional Applications & Engineering Value
This M5 set screw delivers critical engineering solutions where vibration resistance and space constraints challenge conventional fasteners. The cup point design creates permanent indentations in shaft surfaces, providing superior anti-rotation security compared to standard points. Manufactured from alloy steel with Rockwell C45 hardness, it maintains structural integrity under repeated stress cycles and high torque requirements. The 2.5mm hex drive enables precise installation in tight spaces while the Class 5g6g thread fit ensures consistent engagement in metric coarse thread applications. Ideal for securing gears, pulleys, and collars in machinery, automotive, and industrial equipment, this headless set screw provides reliable positioning without protruding components.
Specification Summary & Compliance
This set screw features M5 x 0.8mm metric coarse threads with Class 5g6g thread fit tolerance per ISO standards. The 6mm length and cup point tip provide optimal engagement depth for secure fastening. Manufactured to DIN 916 and ISO 4029 specifications, it ensures dimensional accuracy and performance consistency. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, meeting current environmental standards for industrial components.
