Subsequently, one may also ask, how long should decking screws be?Most decking screws are 8-gauge and, while 2 1/2 inches is the minimum length needed to hold decking boards to the joists, 3-inch screws are commonly used to provide extra holding power against the upward pressure of shrinking or warping boards.Subsequently, question is, is it better to screw or nail decking? Screws are a “superior” fastener over a nail (they have far superior tensile strength)—especially if you’re talking about screwing down decking. Using your deck example—you should use nails to attach the joists to the deck framing but use screws to fasten down the decking itself. Also, what are the best screws for decking? Galvanized screws work well with pressure-treated decking, while Redwood or Western Red Cedar decks are usually built with stainless steel screws to prevent staining around the screw heads.Should I pre drill holes for deck screws?Pre-Drilling Holes: The main benefit of pre-drilling holes for deck screws, or any screws, is simply preventing the wood from splitting. Often this is the only way to prevent splitting when driving screws (or nails) close to the end of a board.
