The screw asylum

Ever wonder what becomes of those screws you find in the box that might have no slot, an uncentered slot, no threads, or odd hunks of metal clinging to them? Wonder no more. They get admitted to The Screw Asylum, where they're diagnosed, photographed, and classified. No information as to whether they're eventually helped on their way to being productive members of hardware society.

(Also, this is my 668th post. Too bad I didn't discover The Screw Asylum a few days earlier, because it would have been a perfect 666th post.)
