Painted Self-Drilling Roofing Screws are high-performance fasteners specifically engineered for roofing applications. These screws combine durability, ease of installation, and superior weather resistance, making them ideal for securing metal roofs, corrugated sheets, and other roofing materials. The integrated EPDM (Ethylene Propylene Diene Monomer) washers provide an excellent seal against water infiltration, ensuring long-lasting protection from leaks.
Key Features:
· Material: High-strength carbon steel with a durable paint finish for enhanced corrosion resistance.
· Finish: Painted in various colors (e.g., black, brown, green) to match or complement the roofing material.
· Drive Type: hex head drive, ensuring secure engagement with screwdrivers and minimizing cam-out during installation.
· Thread Type: Coarse threads optimized for metal and wood substrates, ensuring strong anchoring and easy driving.
· Self-Drilling Tip: Eliminates the need for pre-drilling holes, streamlining the installation process and saving time.
· Integrated EPDM Washer: Provides a watertight seal against water infiltration, ensuring long-term protection from leaks.
· Applications: Ideal for metal roofing, corrugated sheeting, and other outdoor building applications requiring a robust and weather-resistant fastening solution.
