Professional Applications & Engineering Value
Engineered for heavy-duty industrial applications, these M4 socket head cap screws address critical challenges in machinery assembly, automotive components, and precision equipment. The black-oxide alloy steel material provides a protective layer against oxidation and wear, extending service life in harsh conditions. With a Class 12.9 strength grade and Rockwell C37 hardness, they withstand extreme mechanical stresses and repetitive loads without deformation. The fully threaded coarse pitch (0.7mm) design ensures rapid installation and superior clamping force, while the hex drive facilitates torque control in space-constrained environments. Ideal for applications requiring high-strength metric fasteners that meet DIN 912/ISO 4762 standards, these screws deliver consistent performance in automated systems and structural frameworks.
Specification Summary & Compliance
This socket head cap screw features precise M4x0.7mm coarse threads with a Class 5g6g thread fit for accurate engagement and tolerance. Manufactured to DIN 912/ISO 4762 specifications, it ensures dimensional consistency and compatibility. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming adherence to environmental and safety standards for industrial use.
