Sealey Hex Head Zinc Plated Din 7504K Self Drilling Screws 6.3mm 38mm Pack of 100

This 6.3mm diameter by 38mm length variant combines maximum diameter strength with extended length, creating the ultimate fastener for heavy-duty applications requiring both exceptional holding power and deep penetration. The 38mm length is particularly effective for structural connections through thick materials, heavy cladding systems, and industrial applications where fastener failure is not an option. The robust 6.3mm diameter provides superior shear and tensile strength for high-load applications, whilst the 38mm length ensures adequate thread engagement through substantial material thicknesses or multiple layers. The self-drilling point handles heavy-gauge steel with ease, dramatically reducing installation time on demanding projects. The zinc-plated finish guarantees long-term performance.
