Professional Applications & Engineering Value
This M12 metric set screw is engineered to solve critical fastening challenges in industrial settings. The alloy steel material, combined with a Rockwell C22 hardness, provides exceptional shear and tensile strength, preventing failure under high stress. The extended tip and coarse thread pitch ensure secure engagement in components like shafts, pulleys, and gears, reducing the risk of backlash or misalignment. Its square head and external square drive facilitate easy installation with common wrenches, making it ideal for machinery assembly, automotive systems, and heavy equipment where vibration resistance and durability are paramount. By meeting DIN 479 standards, it delivers consistent performance in precision engineering applications.
Specification Summary & Compliance
This set screw adheres to Class 6g thread fit tolerances per ISO metric standards, ensuring precise thread engagement. It conforms to DIN 479 for dimensional accuracy, including head height (12mm), head width (13mm), and length (40mm). The extended tip features a diameter of 8.5mm (-0.22mm tolerance) and length of 3.25mm (-0.25mm tolerance). The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, supporting environmentally responsible and safe industrial use.
