Or, use stainless button head bolts on the inside of the bed through the angle strip (as suggested by Gord), which is what I am doing, and use stainless acorn (cap) nuts on the outside of the bed. In fact, I'm using a lot of s/s acorn nuts on any exposed bolts on the truck ...tailgate brackets, rear light brackets, spare tire mount, etc. Gives it that finished look.
