The Strong-Drive SDWS is the second generation structural timber screw, redesigned with a patented SawTooth Point. It delivers faster starts, less torque, and eliminates the need for pre-drilling, which means more screws installed and less labor for you compared to conventional installation. All this reduces tool wear and extends your battery life! Finished with the Simpson Double Barrier Coating, suitable for interior, treated timber, and external applications.

The SDWS is the advanced alternative to bolting timber, or batten and coach screws, being 30% faster and 10% stronger than an equivalent batten screw. Designed to be versatile, the SDWS is recognized as a solution for timber connections and is backed by testing and load data. It suits outdoor structures, deck frames and ledgers, landscaping, structural timber framing, and replaces strapping, which means no interference with wall cladding. Lintel Screw, Coach Screw, Lag Screw, Landscape Screw, Structural Screw, Ledger Screw, Retaining Wall Screw, Boundary Joist Screw, Deck Post Screw, all are suited.
