Review on HILLMAN 35263 Painted Washer Head Self Piercing by Kevin Webb

I don't know who thought it was a good idea to make these screw heads for a flat head screwdriver. I used these stupid things to attach downspout extensions and what a hassle. Trying to screw them sideways into plastic and metal was so frustrating that I kept cursing and had to attach three extensions. Two bolts each, plus one bolt where the extension goes into the large drain pipe. Why aren't these screws Phillips? The flat head of my screwdriver kept slipping off these screws, and this wouldn't have happened if the screws were Phillips head screws. I don't blame the seller for that. I blame whoever invented this nonsense.
