These are self-tapping screws, meaning that I don't have to drill a pilot hole, but I have broken 3 of them already and I think a pilot hole would help, or maybe a stronger screw.
It seems to break if there is a knothole in the wood or just a harder spot in the wood.
Can anyone recommend a strong stainless steel 3 inch screw that is self-tapping and strong? Would a #10 be better than a #9? Should I just pre-drill with a 1/8 inch drill bit?
I'm using an impact driver (Dewalt XR) and I use it on the middle setting (setting 2 where 3 is max and 1 is for light screwing).
Also, I have no clue about the best way to get the broken screw out (it's just a stub sticking out of the board). Any recommendations for getting the broken screw out?
