Sealey SDHX6325 Self-Drilling Screw 6.3 X 25Mm Hex Head Zinc Pack Of 100

The 6.3mm diameter by 25mm length variant offers the largest diameter in the range, providing maximum strength and load-bearing capacity for the most demanding structural applications. This configuration is particularly suited to heavy steel framework, structural steelwork connections, and industrial equipment mounting where ultimate holding power and shear resistance are critical requirements. The 6.3mm diameter delivers exceptional strength characteristics, making it suitable for high-stress applications where smaller fasteners would be inadequate. The 25mm length provides substantial thread engagement through heavy-gauge materials, whilst the self-drilling point eliminates the need for pre-drilling even in thick steel sections. The zinc-plated finish ensures reliable corrosion protection in industrial environments. Features and Benefits: • 6.3mm diameter x 25mm length for maximum strength applications • Ideal for structural steelwork and heavy industrial fixings • Self-drilling desi
