60 Pieces Round Keyhole Hangers Metal Keyhole Hanger with 120 Pieces Mounting Screws for Mirror Picture Frames (Bronze)

These are very flimsy. The holes for the screws are not counter sunk to hav a flat profile. And when you do screw them down, they bend the crap out of the holder

These are very frustrating to use and are very thin. They're too easy to bend and I can't recommend them for anything above 10 lbs.As mentioned by others, the screw holes are not countersunk, meaning the screw heads stick out in front of the plates and are not flush. Ick.

These brackets are thin and should not be used to hang anything of weight.
