They make self drilling screws for many metal thicknesses. These with flat washers work well.

Cummins, will a self drilling screw just cut right through the wall of a steel frame member under a travel trailer? That's amazing -- the cutting head must be made of heat-treated steel.
I'm assuming you still have to put a lot of upward pressure on the screw and the drill has to be going very slowly, right?
I just bought self drilling hex headed screws at HD when I inclosed the belly of our 5th wheel, no trouble at all.
