Professional Applications & Engineering Value

This M16 set screw is engineered to solve critical challenges in power transmission and precision assembly. The alloy steel material, hardened to Rockwell C45, provides exceptional shear strength and fatigue resistance, preventing failure under cyclic loads. The headless design and cup point allow for flush mounting and deep penetration into mating surfaces, making it ideal for securing gears, pulleys, and collars on rotating shafts. Its metric coarse thread (2mm pitch) and Class 5g6g thread fit ensure quick installation and reliable performance in industrial machinery, automotive systems, and heavy equipment, where vibration resistance and long-term reliability are paramount.

Specification Summary & Compliance

This set screw conforms to DIN 916 / ISO 4029 standards, with a Class 5g6g thread fit for precise metric tolerances. It features an M16x2mm coarse thread, right-hand thread direction, and 100mm length. The product is manufactured to meet RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, ensuring it is free of hazardous substances and suitable for use in regulated environments.
