The SIMPSON STRONG-TIE SDWS22312DBB-R50 is a 3.5-inch black structural screw designed for use with the Outdoor Accents decorative hardware system. It drives without predrilling, reducing installation time on framing and ledger connections. The bold thread pattern delivers strong holding power in wood-to-wood fastening applications. When paired with the separately sold Outdoor Accents load-rated structural washer, the assembly replicates the appearance of a through-bolt connection while simplifying the installation process. This screw is sold in a 50-count pack and is intended for use by carpenters, contractors, and structural fastening professionals working on decks, pergolas, and similar outdoor structures.
This screw is suited for outdoor structural applications including deck ledger attachments, post connections, and decorative framing details. It is designed to work within the Outdoor Accents connector and hardware system, providing a finished look alongside structural performance. The black finish coordinates with Outdoor Accents connectors and washers, which are sold separately. Typical applications include residential deck framing, pergola construction, and other exterior wood-to-wood structural connections where appearance and holding strength are both priorities.
Designed for use within the Simpson Strong-Tie Outdoor Accents decorative structural hardware system. Structural washers and connectors are sold separately and are not included in this pack.
Installation is performed by carpenters or general contractors working on exterior wood-frame structures. No predrilling is required, but fastener placement should comply with applicable building codes and the structural connector manufacturer load tables. Use an appropriate hex or drive-bit driver rated for structural screws. Inspect the connection point for proper wood condition and moisture content before fastening.
