Engineered for long-lasting performance in roofing, cladding, and outdoor applications, the DIN7504K hexagon flange head drilling screw combines strength, precision, and weatherproof protection. Made from high-quality SS304 or SS316 stainless steel, it offers excellent resistance to corrosion, rust, and harsh environmental conditions, making it suitable for both standard and coastal or industrial installations.
The integrated EPDM washer provides a reliable waterproof seal, preventing leaks and protecting the surface from moisture ingress. Its elasticity ensures consistent sealing even under temperature changes or fluctuating pressure. The hex flange head delivers a broad bearing surface, reducing material stress and enabling high-torque fastening for a secure connection.
Equipped with a sharp self-drilling tip, this screw eliminates the need for pre-drilling, allowing for fast, efficient, and accurate installation. Precision-cut threads ensure superior grip and long-term holding power on metal and wood substrates, minimizing the risk of loosening over time.
High-Grade Stainless Steel: SS304 for general use, SS316 for marine and corrosive environments.
