Professional Applications & Engineering Value
This M8 set screw is engineered to address critical challenges in industrial assembly, where vibration, high loads, and precise component alignment are constant concerns. The alloy steel material and Rockwell C22 hardness provide the core strength needed to resist wear and deformation, significantly extending service life in repetitive or high-stress applications. Its square head and external square drive facilitate high-torque installation without cam-out, ensuring a secure clamp every time. The coarse thread with a Class 6g fit offers excellent engagement and resistance to self-loosening, making it a reliable choice for machinery, motor mounts, and structural frameworks. The extended tip further enhances its value by providing a positive location point, simplifying assembly and improving the overall reliability of the fastened joint.
Specification Summary & Compliance
This metric set screw conforms to the dimensional and tolerance requirements of DIN 479. The thread is specified as M8 x 1.25mm with a Class 6g tolerance for external threads. The extended tip features a diameter of 5.5 mm (-0.18mm to 0) and a length of 2.25 mm (-0.25mm to 0). The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations.
