Never seen that before

All 8 bolt heads sheared off

I've been looking after this car for 2 years and I've never removed those bolts before. We found 2 of the bolt heads rattling around the bay. Can't see any reason for it to have happened

Blimey, wouldn't have been over tightened by someone else in the past possibly?
