Pan Head Self Drilling Screws are versatile fasteners designed to drill and tap their own holes in sheet metal, plastics, and composites. They are manufactured to ASTM, DIN, and ISO standards in hardened carbon steel, stainless steel, and brass. The pan head design offers a large bearing surface, making them suitable for secure fastening without surface damage. With self-drilling tips, they allow faster installation, reducing the need for pre-drilling operations. They are widely used in HVAC, electrical fittings, sheet metal fabrication, cladding, and general construction works.
