Efficient fastening with self-drilling screws DIN 7504K 5.5x50 mm

For quick and reliable installation without pre-drilling, the DIN 7504K self-drilling screws with hexagon head and dimensions of 5.5x50 mm are the ideal choice. These screws are specially designed to drill directly into soft metals such as aluminum and various plastics, saving time and effort during the installation process.

High-quality materials for optimal performance

These self-drilling screws are made from stainless steel (A2 quality, AISI 304), providing excellent corrosion resistance. This makes them suitable for both indoor and outdoor applications, even in humid environments. The hexagon head with integrated flange offers extra grip and stability during tightening.
