About Structural Screws (Strong-Drive & Timber Drive)
Heavy deck, dock and framing connections call for fasteners built for the job. Simpson Strong-Tie fastening systems include Strong-Drive and Deck Drive screws, plus the Timber Drive structural screw system, a stand-up tool for driving large structural screws on decks, docks and boardwalks.
The Strong-Drive line includes the SDWS Timber exterior-grade structural wood screw, the SDWS Framing screw and the SDWH Timber-Hex HDG hex-head hot-dip galvanized screw. For waterfront work, the SDWS Timber SS is a Type 316 stainless steel structural screw for docks, piers, boardwalks and saltwater environments, with no predrilling required. Strong-Drive SD and SDS connector screws are used with connectors and holdowns, including the HDUE. The line is built for higher load capacity, corrosion resistance and efficient installation.
Dock and marine contractors along the coast, deck builders and framers all use this line. For a quote, give screw model, diameter, length, finish and box count, and whether you need a Timber Drive tool.
