It is good to replace the original slotted head bolts anyway on all the retrofrictions, as the chrome finish on them tended to rust and flake off very badly.
I don't think those screws were plated at all, I have a NOS set and they look like bare steel to me. I wax them regularly. Button head socket bolts would be out of place on my early seventies bikes.
