Sealey Hex Head Zinc Plated Din 7504K Self Drilling Screws 5.5mm 38mm Pack of 100

The 5.5mm diameter by 38mm length variant combines robust diameter with extended length, creating a fastener designed for demanding applications requiring deep penetration and maximum holding power. This configuration is particularly effective for fixing through insulated composite panels, multiple material layers, and applications where the fastener must span air gaps or cavities. The 38mm length provides exceptional thread engagement for superior pull-out resistance, whilst the 5.5mm diameter ensures the strength to handle high-stress applications. The self-drilling point eliminates pre-drilling even through substantial material thicknesses, significantly reducing installation time. The zinc-plated finish guarantees long-term corrosion resistance in exposed environments.
