Deck Screws — A Range of Material, Coating Compatibilities
Different deck projects require screws with coatings or materials suited to the environment (e.g., stainless steel for coastal areas, coated carbon steel for treated lumber). Having the right screw prevents corrosion and extends the deck’s lifespan.

The Deck Screw You Need, for Wood or Composite
Deck designs use multiple materials and thicknesses. We stock various screws in lengths and thread types to ensure proper holding power and code compliance for joists, railings, decking and fascia boards. This includes screws for wood and composite materials.

Professional Results Require Professional-Grade
Using the best screw for each part of a deck is important in a quality build. Collated screws speed up installation of decking. 6-lobe and square drive heads reduce cam-out or breakage and ensure a cleaner, more professional look with flush or hidden fasteners.
