Do you screw deck boards to every joist?

Screw to every joist. Joists are almost never true (flat) or never stay that way if they are. Pound to a penny the boards'll start bouncing after a while if you don't. If you make sure the lines of screws are nice and straight it really doesn't matter that there's several lines of screws.

Also asked, do you screw decking at every joist?

The screw length is very important; these screws need to penetrate in the joist by 1-1/2 inches. Once all of the decking is in place, snap a chalk line so that the screws can be installed in straight rows over the underlying framing. Each board should recieve 2 screws per joist, spaced about an inch from each edge.

Also Know, 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.

Moreover, how many screws do you put in deck boards?

The general rule of thumb for standard deck fasteners is 350 screws for every 100 square feet of decking, which is based on standard 6” wide boards (5-1/2” actual), and 16” joist spacing.

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.
