The Professional Choice for Thermowood Installations. Specifically engineered for natural wood cladding and decking, these premium stainless steel screws are mandatory for maintain ing the integrity and aesthetics of your Thermowood Ayous project. Why Stainless Steel? Thermally modified wood contains natural tannins that react with standard galvanized or carbon steel fasteners, resulting in permanent black streaks and staining. Our 304/316 Grade Stainless Steel is 100% corrosion-resistant and prevents chemical reactions. Key Features: Trim Head Design: The ultra-slim head disappears into the wood grain for a clean, architectural finish. Star Drive (Torx): Provides maximum torque and prevents stripping during installation. Type 17 Point: Self-tapping tip reduces the risk of wood splitting (pre-drilling is still recommended for ends). Pack Size: 350 Screws (Covers approximately 175 Sq Ft of cladding). ⚠ Required for Warranty: Use of non-stainless fasteners will void the 25-year warranty against rot and decay. Show more
