These match with fairly sturdy protrusions from the fuselage and (to the untrained eye) are pretty hefty mechanisms for holding the plug (or the door frame) in place.
In the picture of the accident aircraft, you can see the four top protrusions from the fuselage (they're pretty obvious) and they appear to have metal in them where the bolts would be. But the frame is completely absent, along with the first parts of those screws/bolts, leaving the rest attached to the fuselage.
It's entirely possible I'm missing something, please (and I'm serious) tell me why I'm wrong.
Those "twelve sturdy protrusions" are the stops that prevent the door being blown out of the aircraft.
If they were bolts through them, nobody would have to worry about the door opening, ever.
I'm pretty sure that's been covered before, more than once.
