Place the first set of fasteners on the joists along the edge of your ledger board, and align them so that the pre-installed screws are in the center of each joist. Screw down at a 45-degree angle into the joist using a power drill with a Phillips-head bit.
Place the first board's groove into the clasp of the fasteners. Use a rubber mallet to tap the board into place if necessary.
Push the next set of fasteners on to the groove in the other side of the first deck board. Align these in the same way as the first set, centering the screws over the center of each joist. Repeat this process as you work away from the first deck board, and toward the opposite end of your deck.
