Professional Applications & Engineering Value
This M12 set screw is engineered to address critical challenges in heavy-duty industrial environments where vibration resistance and permanent fastening are paramount. The Class 8.8 steel construction provides a robust solution for machinery, automotive assemblies, and construction equipment, preventing loosening under dynamic loads. Its extended tip ensures deeper penetration and superior grip on shafts and collars, effectively resisting axial forces. The metric coarse thread with 1.75mm pitch allows for quick installation and high clamp load, while the external hex drive facilitates easy torque application with common tools. By combining high-strength materials with precise DIN 561B specifications, this fastener delivers reliable performance in demanding applications, reducing downtime and maintenance costs.
Specification Summary & Compliance
This set screw features precise metric coarse threading (M12 x 1.75mm) with Class 6g thread fit tolerance for accurate assembly. It complies with DIN 561B manufacturing standards, ensuring dimensional consistency and reliability. The extended tip maintains tight tolerances (tip diameter: 8.5mm with -0.22mm to 0 tolerance; tip length: 6mm with 0 to 0.3mm tolerance). The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, guaranteeing environmental safety and industrial suitability.
