Review on FramePac D Ring Picture Hangers (100 Pack) - Single Hole D-Ring Hanger with Screws - Ideal for Picture Frames, Mirrors, and Framing Professionals by Jessica Lewis

The rings seem fine. I like the shape and the way it's crimped so the rings don't come loose when bent, but the screws that come with it are complete crap. My regular screwdriver just skips and removes the head, and even though I pre-drilled holes in the frame, the screw head sheared off when tightened. I'll see how it goes by hanging more frames, but next time I visit the hardware store I'll definitely pick up better quality screws.
