This screw features a hex flange head with an integrated metal + EPDM bonded washer and a sharp self-tapping point, making it ideal for fastening into materials such as wood, plastic, and thin steel sheets. The sharp, aggressive point provides strong biting force, significantly improving installation speed and efficiency.
The bonded EPDM washer enhances sealing performance and prevents water penetration, ensuring long-term durability in outdoor installations. To resist corrosion, the surface is treated with Thermal Rust-Proof Coating (Ruspert), capable of withstanding 500 to 1000 hours of salt spray testing, which makes it highly effective against humid and high-salinity environments, prolonging product lifespan and reducing maintenance costs.
This type of screw is widely used in roofing, siding, and outdoor wood construction projects.
