Professional Applications & Engineering Value
This M6 socket head cap screw is engineered from black-oxide alloy steel to address common industrial challenges such as corrosion, vibration loosening, and high-load demands. The Class 12.9 strength class and Rockwell C37 hardness make it ideal for heavy machinery, automotive assemblies, and precision equipment where failure is not an option. Its coarse metric thread and fully threaded design facilitate rapid installation and robust clamping force, reducing downtime in production lines. By meeting DIN 912/ISO 4762 standards, it ensures interchangeability and reliability in global engineering projects, while the black-oxide surface treatment resists environmental degradation, making it suitable for outdoor or harsh-condition applications.
Specification Summary & Compliance
This product features precise metric thread dimensions with Class 5g6g tolerance and a coarse M6 x 1 mm thread pitch, manufactured in accordance with DIN 912/ISO 4762 specifications. It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and regulatory adherence for industrial use.
