The CAMO Hidden Deck Fastening System works on treated lumber, hardwood, cedar, composite or PVC deck board. CAMO Hidden Fasteners, a CAMO Marksman tool and CAMO Driver Bits combine to deliver a fastener-free deck surface at a price that makes getting the job easy and installing the deck even easier. The CAMO Hidden Deck Fastening System is engineered to work exclusively together. Using other branded tools, fasteners or bits will impair performance and not produce the desired results.
