Sealey Hex Head Zinc Plated Din 7504K Self Drilling Screws 6.3mm 50mm Pack of 100

The 6.3mm diameter by 50mm length variant represents the ultimate option in the Sealey DIN 7504K self-drilling screw range, combining maximum diameter strength with the longest available length. This configuration is specifically designed for the most demanding structural applications requiring exceptional holding power and deep penetration through thick or multiple material layers. The 50mm length provides superior thread engagement for critical connections, whilst the 6.3mm diameter delivers maximum shear and tensile strength for high-load applications. This variant is ideal for heavy structural steelwork, thick insulated panel systems, and industrial mounting applications where fastener performance is paramount. The self-drilling point efficiently penetrates substantial material thicknesses, and the zinc-plated finish ensures long-term reliability.
