It almost looks like the hinge mortise on the door was made deeper to accommodate the hex head screws when the door is closed. Obviously this door didn’t originally fit this frame – the hinge prep sizes are different – probably 5″ on door and 4 1/2″ on frame.
I noticed that the mortise was a little too deep but I doubt that it accommodates the hex-head bolts. I’m headed to NYC next month…maybe I’ll have to take a detour and try to close this door. 🙂
Since the hinge is not NRP, maybe they were going for Security Studs? Just kidding, but I have heard of taking one screw out and backing off the screw that is opposite the missing screw to accomplish the same thing. You have to grind down the head a bit so it fits deeper in the hole.

That’s interesting…I’ve never seen that! I’m pretty sure that’s not what they were going for here, though. 🙂
