1/4'' x 5/8" EPDM Bonded Sealing Washers

The Black EPDM (Ethylene Propylene Diene Monomer) bonded washer is a specialized component designed to enhance the performance and longevity of roofing screws. It consists of a metal washer bonded to a layer of EPDM rubber, which provides several advantages in roofing applications.
EPDM Rubber Material is highly resistant to UV radiation, ozone, and weathering, making it ideal for long-term outdoor use. The rubber forms a watertight seal around the screw head, preventing water infiltration and leaks. The metal washer provides additional strength and stability, helping to distribute the load of the screw over a larger area. The metal washer are often made of galvanized steel or stainless steel, which are resistant to rust and corrosion. The EPDM rubber is securely bonded to the metal washer, ensuring a strong and reliable connection.
