Professional Applications & Engineering Value
These M4 socket head cap screws deliver outstanding engineering value in demanding industrial environments where failure is not an option. The Class 12.9 alloy steel construction provides exceptional resistance to vibration loosening and fatigue, making them ideal for heavy machinery, automotive assemblies, and precision equipment. The blue-dyed zinc plating offers both corrosion protection and visual identification benefits in complex assemblies. With their 3mm hex drive and standard socket head profile, these metric hex socket screws allow for high torque application in confined spaces where traditional fasteners cannot be used. The M4x0.7 coarse thread ensures quick assembly and reliable performance even in challenging conditions, while the fully threaded design provides maximum grip length for secure fastening in various material thicknesses.
Specification Summary & Compliance
These precision metric fasteners feature M4 thread size with 0.7mm pitch coarse thread spacing and Class 5g6g thread fit tolerance, ensuring precise engagement and reliable performance. Manufactured to DIN 912/ISO 4762 specifications for dimensional accuracy and interchangeability. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, making them suitable for global industrial applications with strict environmental requirements.
