EPDM Rubber Washer: The EPDM rubber washer is the most critical component of these roofing screws. EPDM is a synthetic rubber material known for its excellent weather resistance, UV resistance, and durability. The washer is bonded to the underside of the screw head and acts as a seal between the screw and the roofing material, preventing water infiltration and potential leaks.
Thread Design: EPDM bonded washer roofing screws typically have coarse threads designed to grip into the roofing material and the underlying structural support effectively. Some screws may have self-drilling or self-tapping points to facilitate easy installation without the need for pre-drilled pilot holes.
Head Types: These roofing screws come in various head types, including hex head, washer head, and pancake head, among others. The choice of head type depends on the specific application and desired appearance. Hex head screws are commonly used for applications where a wrench or socket is required for installation, while washer head and pancake head screws provide a larger bearing surface for distributing the load and enhancing pullout resistance.
Materials: EPDM bonded washer roofing screws are typically made from hardened steel, stainless steel, or other materials with high strength and corrosion resistance. The EPDM rubber washer provides additional protection against corrosion and weathering, ensuring long-lasting performance in outdoor environments.
Size: These roofing screws come in various lengths and diameters to accommodate different roofing material thicknesses and installation requirements. The most common lengths for roofing screws range from 1 inch to 3 inches, with longer lengths used for thicker roofing materials or when attaching to thicker structural supports.
Applications: EPDM bonded washer roofing screws are widely used in roofing applications for residential, commercial, and industrial buildings. They provide a secure and watertight fastening solution while also protecting against leaks and water damage in the roof assembly.
