The CAMO Edge Deck Fastening System is a fast, easy, and affordable way to install a fastener-free deck surface. Patented CAMO Edge Deck Screws are installed through the edge of the board—not on the surface—and are secured directly to the joist which reduces board movement. There’s no pre-drilling required when you use Edge Deck Screws with Pro, Pro-X1, Pro-NB, and Edge Guides. Edge Deck Screws have a patented rake tip that auger out material, which reduces splitting and cracking, plus their ProTech coating passes a 1500-hour salt spray test. Edge ProTech Coated Deck Screws can be used on treated lumber, composite, capped composite, and PVC decking. Two T15 Star drive bits included.
