Question for you pro's when installing 5/4 PT deck boards do you pre drill/countersink the screw holes ? Or are the deck screws designed to just drive them in ? I will be using a cordless torque driver and do my best to just get the head of the screw below the surface . I plan on using 2 1/2 " long deck screws . I think all these screws are now Torx bit which I feel is superior to Phillips .
