Simpson 5.5" T-40 Double Barrier Screws Black 50ct SDWS22512DBB-R50

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 5-1/2-in screw features a bold thread design that enables superior holding to attach ledgers and other secure connections.
