Sealey SDHX4813 Self Drilling Screw 4.8 x 13mm Hex Head Zinc DIN 7504K Pack of 100

The 4.8mm diameter by 13mm length variant steps up in diameter to provide increased strength whilst maintaining a short overall length, making it ideal for heavy-duty applications where space is limited. This configuration is particularly suited to structural fixings, heavy gauge sheet metal, and applications requiring higher shear and tensile strength in a compact fastener. The 4.8mm diameter provides significantly enhanced holding power compared to smaller variants, whilst the 13mm length keeps the profile low for flush-mounted installations. The self-drilling point handles thicker materials with ease, and the zinc-plated finish ensures durability in challenging environments. The hex head accommodates standard 8mm sockets for secure tightening. Features and Benefits: • 4.8mm diameter x 13mm length provides enhanced strength in compact format • Ideal for heavy-duty applications and structural fixings • Self-drilling point handles thicker gauge materials • Zinc-plated finish ensures lo
