CAMO Stainless Steel Deck Screw The CAMO Hidden Deck Fastening System works on any treated lumber, hardwood, cedar, composite or PVC deckboard. CAMO deck screws, 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 won't produce the desired results. For use with any nominal 5/4 1 In. x 5-1/4 In. to 5-3/4 In. solid or grooved deckboards. #316 Stainless Steel is the ultimate in corrosion resistance; recommended for coastal environments. A reverse rake tip removes deck material as it bores, allowing the screw to penetrate the board without splitting.. A star drive offers more points of contact for better performance and reduces bit slippage and wear.
