Major fastener manufacturers produce screws made specifically for composite decking. Use of these screws will reduce the amount of predrilling and countersinking required. For ease of installation, we recommend using 2-1/2" corrosion-resistant, composite wood deck screws. These screws help minimize the common "mushroom" effect that sometimes occurs when using standard fasteners. We recommend the Stowaway™ Hidden Fastener. We recommend using broad-head stainless steel 2" nails with Fastendry. If traditional fastening through the top of the decking is preferred, but a fastener-free appearance is still desired, Pro Fastening Systems are the fastest, easiest way to hide deck screw heads on stairs, perimeter boards or when replacing a deck board.
