Drill a pilot hole first like you say you are going to do. Then, put a
little candle wax on the threads. This will make them go in much easier.

I am going to have to install 8 or 10. 3/8 or 1/2 for a roof tarp.
It there a way to drive them with a battery drill.
I am thinking about at least drilling the hole a little smaller than
the screw.
