Hi Binty,
As the deales said, its a common problem but I have never heard of one with self tapping screws before.
They usually have expansion plugs with push in centres (similar to the fixings in the door cards) and are very easy to replace useing a small thin screwdriver etc to push the center tapered pins through and release the plugs.
Holding the hinge firmly against the car body, a tap with a small hammer on the end of a short thin piece of wooden doweling held against each protruding pin in turn should fix the expansion plugs properly seated in their holes
