Fulfill the fastening needs of your outdoor project with Power Pro composite deck screws. Specially designed to fasten composite decking, treated wood and other plastic materials, the gray star-drive composite deck screw will blend perfectly with your decking project. Recommended for use in ACQ, CA and CCA treated lumber, the ceramic coating on this screw is able to withstand high temperatures while providing superb rust and corrosion protection. Engineered with pro-cut threads that reduce splitting and a self-drilling tip, installation is made simple with no need for a pilot hole. The trap head and star drive on this screw aid to prevent mushrooming and lowers the torque for a smoother drive.
