With the square on them to maintain orientation I think they may be considered a type of carriage bolt (if I’m remembering the terms correctly) and their heads were painted red over a plating that was probably zinc. The oval bolts were similarly plated but with their stainless caps polished and I believe that was a one-time thing with the plating done before the caps were crimped into place. It is probably better to locate reproductions or even NOS bolts.
