Driven To Exceed Expectations
In the fastener marketplace, Simpson Strong-Tie stands apart from the rest. Quality and reliability is our top priority. That’s why we hire PHDs, metallurgists, materials engineers, and structural engineers to create the best possible fasteners. And why each production run goes through rigorous testing to ensure our products can handle higher loads, resist corrosion, and make installation more efficient.
Pull all your outdoor projects together
The Strong-Drive® SDWS TIMBER Screw is designed to provide an easy-to-install, high-strength alternative to through-bolting and traditional lag screws; great for ledgers too. SDWS structural wood screws are ideal for the contractor and do-it-yourselfer alike.
Versatility That Works
The Deck-Drive™ DCU COMPOSITE screw works in all types of composite decking (composite and encapsulated composite). It provides a cleaner, less noticeable installed appearance and is available in 11 colors, matched to blend with most composite deck products.
