when replacing rivets with grade 8 hardware in crossmembers/hangers, etc, should normal washers be used under the nut and bolt head on each side of the frame as well?

On my DJM hangers, I upgraded the size by one and installed grade-8 hardware---Installed washers on both sides. The first time w/o washers behind the bolt head, the heads wanted to go through a bit.

BTW, I take back my previous reply about not welding in a notch. Do not bolt and weld a notch in---Do one or the other.
