Professional Applications & Engineering Value
These M6 socket head cap screws deliver critical engineering solutions where high tensile strength and reliable fastening are paramount. The black-oxide alloy steel construction provides superior protection against corrosion in manufacturing equipment, automotive assemblies, and heavy machinery. With Class 12.9 strength rating (170,000 psi) and Rockwell C37 hardness, these metric fasteners withstand extreme vibrational loads and dynamic stresses. The fully threaded right-hand design with coarse pitch threads ensures rapid installation and maintains joint integrity in high-vibration environments. The 5 mm hex drive socket enables high torque application without stripping, making them ideal for precision assembly applications requiring repeated maintenance access.
Specification Summary & Compliance
Manufactured to DIN 912/ISO 4762 specifications with Class 5g6g thread fit tolerance for precision engagement. Features M6x1 mm coarse threads in right-hand direction with 18 mm fully threaded length. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. Class 12.9 strength classification ensures mechanical reliability for industrial applications.
