I am considering the use of outdoor rated pocket hole screws to attach 5/4 Trex decking to 2x joists on my 15x20 deck. The deck varies 15-24 inches off the ground so there is room to work from underneath if necessary. Ignoring the additional TIME & LABOR it would take to drill a significant number of holes, has anyone tried this type of installation? I have the K3 system and the mini and was planning on using the mini. Clamping the board in place, then clamp the mini to the desired location for the hole, drill, screw and move on. I have tested on scraps and with the correct clutch setting on the drill; I have had no issues with the screws holding in the Trex decking. Comments or concerns?
