Self tapping screws will work if you drill out the holes first. You can save a step by using self drilling screws....these are acctualy called TEK screws, they have a built-in drill point on the tip, once they drill through the metal, the threaded section takes over and pulls the screw into place... You can find these at pretty much most fastner paces, I think even Lowes carries a limited selection of these...
I have used TEK screws almost exclusively on my bus. They have saved me a whole lot of drilling... At first I'd drill, then either use self tappers or pop rivets... the TEK screws really saved me that extra step...
BTW.... phillips head works pretty well, but a square drive head works even better!!
