There’s no pre-drilling required with the new DeckWise® Self-Drilling Deck Screws. Their nail point tips can penetrate the densest exotic hardwoods, such as Ipe and the serrated thread design prevents your deck boards from splitting or splintering, even when drilling near the edge. DeckWise® Self-Drilling Deck Screws are heat treated for hardened toughness and feature a patented TTAP® T15 Star Drive head with locking bit to eliminate slipping, so you won’t have to worry about broken screws or stripped heads. Engineered exclusively for DeckWise®, the Self-Drilling Deck Screws make installing hidden deck fasteners easier than ever.
