New exhaust system rubber has come out on hangers

I went back and looked at the pic again this morning. From what I can see there is nothing keeping the rubber grommet from backing out. If the rod has no washer welded on the backside where it contacts the grommet it will back out no matter what. At first I thought that the bracket had rotated but now I can see that even if the bracket hadn't rotated the grommet could still back out. Is there a large washer welded onto the rod on the backside where the grommet is backing out?? Also it almost looks like the exhaust pipe is very close to the bracket, is it touching or would it touch under vibration.....if so it needs more clearance.
