Like they sound, deck screws are corrosion-resistant screws that are used in the building of outdoor decks. Deck screws reduces warping of the deck wood and hold strong like a rivet. This type of screw is easier to fasten than conventional wood screws, and doesn’t require pre-drilling the deck wood. Nuts and bolts not necessary. Zoro also has a super selection of wood screws and multi-material screws too.
