The Outdoor Accents structural wood screw reduces installation time by driving easily without predrilling. When combined with the patented, load-rated Outdoor Accents hex-head washer, the solution delivers the decorative appearance of a bolt connection but with a much easier installation. The structural wood screw can be used with either the Mission Collection® or Avant Collection™, as well as separately to add flair to any outdoor project. The 3-1/2 in. screw features a bold thread design that enables superior holding to attach ledgers and other secure connections. Outdoor Accents® Structural Wood Screw — .220 in. x 3-1/2 in.
