2024.07.15 Self Drilling Screws Roofing Screws: Exceptional Quality for Your Roofing Needs
Features and Specifications
Hex Washer Head Design:
Our Roofing Screws predominantly feature a hex washer head. This head type is highly effective when drilled into sheet metals on roofs, offering a robust and even grip on the washer placed beneath it.
Washer Integration:
Each Roofing Screw is paired with a washer inserted under the hex washer head. Common types of washers used include EPDM rubber washers, bonding washers, and umbrella washers. When fastened, the hex washer head compresses the washer against the surface, creating a watertight seal that prevents water penetration.
Thread and Point Design:
The coarse threading of our Roofing Screws is designed to securely hold the sheet metal roof to the wood or metal studs. Additionally, the screws feature a self-drilling point, enabling them to easily penetrate thin sheet metals and the underlying material, ensuring a strong and secure attachment.
Surface Coatings and Color Options:
Our Roofing Screws are available in various coatings, including zinc and yellow zinc, which provide enhanced corrosion resistance. For superior protection, we also offer mechanically galvanized coatings (C3, C4). Furthermore, we can customize the color of the screw heads to match the color of your sheet metal, using the international color chart to meet your specific requirements.

DD Fasteners offers Roofing Screws in a range of standard diameters and lengths to suit different roofing applications. Whether you need shorter screws for thinner materials or longer ones for thicker substrates, we have the right size for your project.
