Yes they do!
I use them for that purpose all the time. If the hanging is small and under a couple pounds, one does the trick. For heavier items I might use four...two together on either side of the frame. I also have put one on each side corner at the bottom of the frame to act as a "ledge" on which to rest the frame.
They leave virtually no visible hole at all.
