Antrader Heavy Duty Keyhole Hangers,Single Hole Hanging Plates for Picture Frames Mirrors Cabinet with Screws,Black 1.8" x 0.65", 10 Pack

it works, well made. required a more complex counter bore than I thought at first. Main issue is that screw placement on wall becomes position critical, not much tolerance for error. Compared to a key hole cutter this is easily doable on a drill press but the positional accuracy required for the wall screw is MUCH more critical.

This was exactly what I needed. It's a tight concept with the mounting screws so close. The included screws are high quality and a great shape making for a sturdy install. The metal is thin enough to not stand out, and thick enough to be very strong. Saved my project.

Out of the 24 that I received, 2 were completely useless as they were properly punched out. At least another 7 had one of the holes slightly off. See attached pictures. The rest were fine to use, but also had one of the holes a little off; it's clear that the press that makes these needs to be aligned/adjusted. Regardless, assuming you just some of these (not all 24), they are a good value. In a lot of applications, these will be in the back and not seen, so they should work fine for that. I used them to hang some wooden planks and had no issues when I selected the higher quality ones. Take your time if using the included screws, as you can easily round out head.

Rated at 40lbs, I would not try it. Great for about 25lbs .very well made just not as heavy duty as others. This product is the one on right in my pic

The media could not be loaded.  I’ve used these several times to hang things flushly to the wall, from kitchen signs I custom made to wooden crosses and plaques. They work well, but you need to be careful when screwing them in. The screw holes can be stripped if you aren’t careful and put too much force driving the screws in.

Works as needed. Easy to install. Good value as multi-pack for multi-projects or add to hardware collection for future use.

I used these to make flower vase sconces. They weigh a couple pounds, easy to install, used a drill but you could probably do by hand if you had to. Sits nice and flush to the wall

I have not hung anything with them but they look and feel like they will do the job I bought them for.
