Professional Applications & Engineering Value
These M4 flat head socket screws deliver exceptional engineering value in precision assemblies where surface flushness and corrosion resistance are critical. The 18-8 stainless steel material, enhanced by passivated finish, effectively resists oxidation and chemical exposure in manufacturing equipment, automotive components, and electronic enclosures. The coarse thread pitch (0.7mm) combined with Class 6g tolerance ensures rapid installation and secure holding power in metals and plastics, reducing the risk of cross-threading. The fully threaded design along the 30mm length accommodates varying material thicknesses, while the hex drive provides superior torque transmission compared to Phillips or slotted drives, minimizing tool slippage and damage in high-volume production environments.
Specification Summary & Compliance
This metric screw features M4 x 0.7mm coarse threads with Class 6g thread fit according to ISO metric standards, ensuring precise dimensional compliance. Manufacturing specifications strictly adhere to DIN 7991 / ISO 10642 for flat head socket cap screws, guaranteeing consistent head profile, countersink angle (90°), and drive size (2.5mm hex). The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, containing no restricted substances above threshold limits, making it suitable for global industrial supply chains.
