• Maximum hardness and durability at Rockwell C37, providing excellent wear resistance and long-term mechanical integrity.
• Full thread coverage along the 12 mm length offers versatile fastening options and uniform stress distribution.
• Global compliance assurance meeting DIN 912/ISO 4762, RoHS 3, and REACH standards for quality and environmental safety.

Professional Applications & Engineering Value

This M6 socket head cap screw is engineered from black-oxide alloy steel to address critical challenges in high-stress mechanical assemblies. Its Class 12.9 strength rating and 170,000 psi tensile strength make it ideal for applications where vibration, heavy loads, and dynamic forces are common, such as in machinery, automotive systems, and precision equipment. The fully threaded design with coarse pitch ensures rapid installation and robust clamping, while the hex drive and standard socket head profile facilitate easy access in confined spaces. By combining high hardness (Rockwell C37) with corrosion-resistant black-oxide treatment, this screw minimizes maintenance needs and enhances operational reliability in industrial settings, supporting efficient production and reduced downtime.
