National Nail Corp.’s Camo Hidden Deck Fastening System, part of the Pro-Fit brand, is a hidden deck fastening system that attaches lumber, hardwood, cedar, and composite or PVC deckboards directly to a substructure. The system includes both deck screws and Marksman tools that enable a side-angle entry that secures solid or grooved deckboard directly to the joist, reducing board movement and allowing screws to be hidden. No pre-drilling is required, and a specially designed driver bit, a Marksman tool, and a cordless drill are all that are needed for installation.
