Camo® Deck screws create a beautiful, fastener-free deck surface. Easy-to-install using either Marksman® tool, Camo® secures deck boards directly to the joist to reduce board movement and they back out easily in the event a board needs to be replaced. No pre-drilling is required and Camo® deck screws come with a Limited Lifetime Warranty that assures against rust and corrosion for the life of the project.
