Hex Head Self Drilling Screw + EPDM Washer:4.8 x 75mm (3") - DIN 7504K

The Hex Head Self Drilling Screw + EPDM Washer is a fastening solution designed for direct attachment to thin metal substrates without pre-drilling. It features a nominal diameter of 4.8 and a nominal length of 75mm, conforming to the DIN 7504K standard. The inclusion of an EPDM washer provides a sealed interface, helping to prevent moisture ingress at the fastening point. Buyers often select this configuration for applications requiring reliable weather protection combined with the speed of self-drilling installation. To choose the appropriate size, assess the thickness of the material being joined to ensure the 75mm length provides adequate grip, while verifying that the 4.8 diameter aligns with the specific load requirements of the assembly.
