Professional Applications & Engineering Value
Engineered for demanding industrial settings, these M4 metric screws with zinc-plated steel offer robust protection against corrosion and wear. The coarse thread (0.7 mm pitch) and fully threaded M4 x 22mm design provide quick installation and reliable holding power in materials like metal, plastic, and wood, reducing the risk of stripping. The flat head with standard countersink ensures a smooth, flush finish, ideal for applications where protrusion is a concern, such as machinery assembly, automotive components, and electronic enclosures. With a Rockwell B71 hardness and high tensile strength, these screws address common issues like loosening under vibration and environmental degradation, delivering consistent performance in industrial screw applications.
Specification Summary & Compliance
This product features precise metric thread specifications with M4 size, 0.7 mm pitch, and Class 6h thread fit per ISO standards, ensuring dimensional accuracy and compatibility. Manufactured in accordance with DIN 965 for flat head screws, it meets rigorous engineering guidelines. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, it is free from hazardous substances, supporting safe and sustainable industrial use.
