Self Drilling Screws with EPDM Washer M5.5*40
Self-drilling screws with EPDM washers are a type of fastener that combines the functionality of a screw and a drill bit. They have a sharp point that can pierce through metal, wood, or other materials, eliminating the need for pre-drilling. The EPDM washer, which is bonded to the head of the screw, provides a watertight seal, preventing leaks and protecting the underlying material from corrosion.

Crafted from high-grade materials (typically carbon steel with galvanized or stainless steel finishes, customizable by requirement), the screws offer excellent resistance to corrosion, weathering, and outdoor environmental stress—critical for maintaining structural integrity in roofing systems exposed to rain, UV rays, and temperature fluctuations.
