Professional Applications & Engineering Value

This M8 set screw is engineered to address critical fastening challenges in precision assemblies. Manufactured from alloy steel and heat-treated to a Rockwell C45 hardness, it provides exceptional shear and tensile strength, preventing failure in high-stress applications. The headless hex drive design is ideal for securing collars, pulleys, and gears onto shafts where a flush finish is required, eliminating interference and maintaining rotational balance. The coarse thread (1.25mm pitch) and Class 5g6g thread fit ensure quick assembly and reliable clamping force, reducing installation time while maintaining joint integrity. Compliant with DIN 913 and ISO 4026 standards, this metric set screw delivers consistent performance in machinery, automotive, and automation systems, offering a dependable solution for permanent or semi-permanent fastening needs.

Specification Summary & Compliance

This set screw features an M8 x 1.25mm coarse thread with a Class 5g6g thread fit per ISO metric standards, ensuring dimensional accuracy and interchangeability. It is manufactured to meet DIN 913 / ISO 4026 specifications for headless set screws with hex socket drive. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming the absence of restricted hazardous substances and adherence to environmental and safety standards.
