Have you looked down the holes to see what's there? Do you think maybe lag bolts onto wood? Or (horrors!!) were you supposed to use a nut before the plywood ceiling panel went in?
You might consider nutserts. They're like an oversized pop rivet but threaded on the inside. You insert them into a slightly oversized hole then a special tool draws it up from the bottom locking it in place in your roof sheet metal. When the tool is removed it leaves the threaded insert there to take your hex bolt.
