3.5mm x 13mm Countersunk Self-Drilling Screws (Zinc Plated)

ISO 15482 Zinc-Plated Countersunk Self-Drilling Screws for Metal Fixing

These ISO 15482 screws are zinc-plated countersunk self-drilling screws for metal fixing, commonly used in roofing, cladding, and window installations. A tapered, self-drilling point bites cleanly into the material, while the countersunk head sits flush with the surface for a neat finish. Manufactured from carbon steel and finished with white zinc plating, they resist corrosion and are suitable for interior and light exterior use.
