Simpson Strong-Tie 5-1/2 in. SDWS Structural Wood Screw

The Simpson Strong-Tie 5-1/2 in. SDWS Structural Wood Screw provides heavy-duty structural fastening designed to significantly reduce installation time. Featuring a patented SawTooth point, it eliminates the need for pre-drilling in most wood-to-wood applications while reducing driving torque. When used alone or paired with decorative hex head washers, it provides the holding power of a traditional bolt connection with fast screw installation. Equipped with a deep six-lobe recess for positive engagement and a black double-barrier coating for corrosion resistance, this fastener is ideal for ledgers, pergolas, timber framing, and outdoor living structures.
