You need to find a place that sells nothing but fasteners, they might have something closer then that sheet metal screw. The only other option is to break out a tap and die set and modify the holes to accept machine screws. One of the old radio parts venders supposedly sells replacement chassis screws for Philcos but I have a feeling that they are just sheet metal screws like the second ones you have.
