Professional Applications & Engineering Value

These M3 socket head cap screws deliver exceptional engineering value in demanding applications where failure is not an option. The Class 12.9 strength rating and 170,000 psi tensile strength make them ideal for high-stress assemblies in machinery, automotive components, and industrial equipment. The zinc-plated alloy steel construction provides reliable corrosion protection while maintaining the Rockwell C37 hardness needed to resist wear and deformation. The hex socket drive design allows for high torque application in confined spaces, while the coarse thread pitch ensures quick assembly and secure fastening in various materials. These metric screws are engineered to prevent loosening under vibration and maintain clamping force in the most challenging industrial environments.

Specification Summary & Compliance

These socket head cap screws feature precise M3 x 0.5 mm thread specifications with Class 5g6g thread fit tolerance for consistent performance. Manufacturing complies with DIN 912/ISO 4762 standards for dimensional accuracy and quality assurance. The fasteners are fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring they meet the latest industrial safety and sustainability requirements. The right-hand thread direction and fully threaded design provide uniform load distribution across the entire 15 mm length.
