Professional Applications & Engineering Value

This M4 socket head cap screw is engineered to address critical challenges in high-stress industrial settings, such as machinery assembly, automotive systems, and precision equipment. Made from Class 12.9 alloy steel, it combines high tensile strength and hardness (Rockwell C37) to prevent stripping and deformation under heavy loads. The blue-dyed zinc-plated surface provides reliable corrosion resistance, ideal for environments exposed to moisture or chemicals. With a 3mm hex drive and coarse metric thread (M4 x 0.7mm), it ensures rapid installation and secure fastening, reducing downtime in production lines. Its partially threaded design allows for precise clamping in applications where full threading isn't required, enhancing versatility in industrial fastening solutions while meeting strict DIN 912/ISO 4762 specifications for reliability.

Specification Summary & Compliance

This screw features precise metric dimensions including a 50mm length, M4 thread size with 0.7mm pitch, and Class 5g6g thread fit for accurate assembly. It adheres to DIN 912 and ISO 4762 standards for socket head cap screws, ensuring consistent quality and performance. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its safety and environmental responsibility in industrial use.
