Multi-Material No. 10 Label X 3-1/2 In. L T-20+ Flat Head Serrated Construction Screws

Spax flat head multi-material construction screws are engineered to fasten securely across wood, drywall, masonry, sheet metal, and plastic. These versatile fasteners solve the problem of needing different screws for different materials—one product works reliably on most common building substrates. The #10 x 3-1/2 inch size suits deck building, siding installation, framing, and general construction and repair work.

Built with a patented 4Cut Point tip that starts the thread cleanly, these screws prevent splitting and eliminate the need for pre-drilling in wood, saving time on every application. The T-Star Plus drive resists slipping during installation, while the flat head delivers a clean, finished appearance. Patented thread serrations reduce driving torque, helping extend power tool battery life during extended use.
