Sealey Hex Head Zinc Plated Din 7504K Self Drilling Screws 4.2mm 13mm Pack of 100

This 4.2mm diameter by 13mm length variant is the most compact option in the Sealey DIN 7504K self-drilling screw range, making it ideal for applications requiring a shorter fastener with excellent holding power. The 13mm length is particularly suited to fixing thin sheet materials, ventilation components, and light-duty brackets where a low-profile fixing is essential. The 4.2mm diameter provides adequate strength for general-purpose applications whilst minimising the material displacement during installation. The zinc-plated finish ensures reliable corrosion protection, and the self-drilling point eliminates the need for pilot holes, dramatically reducing installation time on repetitive tasks. The hex head design allows for secure tightening with standard 7mm sockets or hex drivers. Features and Benefits: • 4.2mm diameter x 13mm length ideal for thin sheet materials and low-profile applications • Self-drilling point eliminates pre-drilling for faster installation • Zinc-plated finish
