Sealey Hex Head Zinc Plated Din 7504K Self Drilling Screws 5.5mm 50mm Pack of 100

This 5.5mm diameter by 50mm length variant represents the longest option in the 5.5mm diameter range, making it ideal for applications requiring maximum penetration depth whilst maintaining excellent strength characteristics. The 50mm length is particularly suited to fixing through thick insulated panels, timber-to-steel connections, and applications where materials must be secured across substantial gaps. The combination of 5.5mm diameter and 50mm length provides exceptional versatility for complex fastening challenges. The extended length ensures adequate thread engagement even when penetrating multiple layers or spanning cavities, whilst the robust diameter maintains structural integrity under load. The self-drilling point cuts efficiently through varied materials, and the zinc-plated finish ensures reliable performance.
