Review on Applied Magnets Countersunk Neodymium Magnet by Andy Baker

These magnets are NOT regular magnets. It's very strong. Small screws can pose a problem when these magnets are not attached to a solid object. They couldn't just be screwed into drywall - which is why if you're attaching something with a lot of metal and try to remove that item from the magnet, the strength of the magnet combined with the small screw pulls itself away from the wall. Be careful when separating, because I speak from experience, you will get your fingers caught. If you need to hang some meta, this is what you need. I would strongly advise against using them in your fridge lol. Great product, strong magnets.
