Daggerz™ Bugle Deck Screws are offered in both Phillips and Square Drive with Zinc, Dacromet, and ACQ coatings. For harder woods, there are Phillips, Square, and Star Drive Deck Screws with type 17 points that eliminate pre-drilling and enable a smooth penetration. These Daggerz™ Deck-Pros also have Nibs under the heads to help prevent spin out and allow the screws to self-countersink.
