The Simpson Strong-Tie SDWS22312DBB .220 x 3-1/2" Outdoor Accents® structural wood screw reduces installation time by driving easily without pre-drilling. When combined with the patent-pending, load-rated Outdoor Accents STN22 structural washer, the solution delivers the decorative appearance of a bolt connection but with a much easier installation. The structural screw and washer are sold separately from each other and from the Outdoor Accents connectors. The screw's bold thread design enables superior holding to attach ledgers and other secure connections.
