So I am leaning toward self drilling self tapping screws. I am planning to drill a pilot hole -- I will experiment to see what size pilot will give me the best results.
I am leaning toward hex head screws -- I have a tendency to strip Phillips screws when working upside down, and hex heads give me a nice solid grip, so that I can snap the head off a few of the screws by over-tightening them.
I'd drill a pilot hole and use Canadian invented #2 Robertson square head self tapping screws ... with a properly sized pilot hole a cordless drill will easily secure the screws tightly without fear of twisting the head off. Robertsons may be harder to source in the US but are FAR superior to those awful American invented Philips head screws. :p
YEA OK! I have used thousands of both type screws in construction. Phillips work great for drywall application and Sq Drive (Roberts) work sell for cabinet installation.
The both work well as long as your bit tip is a quality one that is the correct dimensions for the screw being used.
Hex head driller screws that have a washer built into the head for more surface contact. Driller portion needs to be longer than the thickness you are driving into. If the material is thin same screw with sheet metal threads, no need to pre drill.
Use an impact and learn to feather the trigger.
