Deck Screws

Chan Chin C. Deck screws are specially designed to eliminate the mushrooming and blemishes that can occur on composite materials. Since wood decks have many thin planks and must withstand harsh environmental conditions, deck screws are designed to accommodate the challenges of this application. Deck screws must resist corrosion, drive easily, and lay smoothly against the deck surface, called countersinking. For these reasons, many deck screws are self-countersinking, self-drilling, and coated with materials that won't rust.
