S-94048A417 Length 9" ASME B18.2.1, ASTM A307, SAE J429 Wood Screws

Key Features & Benefits at a Glance

• Exceptional corrosion resistance with hot-dipped galvanized steel coating for long-lasting performance in outdoor or humid environments
• Maximum torque transmission through external hex drive design, preventing cam-out during high-torque installation
• Superior holding power with partially threaded design that pulls wood components tightly together while minimizing wood splitting
• Enhanced thread engagement with thread forming tapping method that creates strong, permanent connections in wood materials
• Heavy-duty construction with 1/2" diameter and 9" length for demanding structural wood applications
• Reliable installation with pointed tip design for easier starting and reduced pre-drilling requirements
• Industry-standard compatibility meeting ASME B18.2.1, ASTM A307, and SAE J429 specifications for consistent performance

Professional Applications & Engineering Value

These hot-dipped galvanized steel wood screws deliver exceptional engineering value for heavy-duty wood construction and industrial applications. The external hex drive provides superior torque transmission capability, eliminating the common problem of screw head stripping during high-torque installation in dense woods. The partially threaded design creates a clamping action that pulls wood members tightly together while minimizing the risk of wood splitting that often occurs with fully threaded fasteners. With 6 threads per inch and thread forming technology, these screws develop maximum pull-out resistance in structural wood connections, making them ideal for timber framing, deck construction, and outdoor structural projects where vibration resistance and long-term reliability are critical.
