Hex Head Self Drilling Screw

Hex Head Self Drilling Screws with EPDM Washers are heavy-duty fasteners designed for roofing, cladding, and structural steel applications. They are manufactured to ASTM, DIN, and ISO standards in hardened carbon steel or stainless steel, combined with bonded EPDM washers. The self-drilling tip ensures fast installation without pre-drilling, while the EPDM washer provides a durable, watertight seal. These screws offer excellent resistance to corrosion, vibration, and weather conditions, making them suitable for outdoor use. They are widely used in roofing sheets, metal cladding, steel framing, and industrial building applications.
