I wanted some kind of magnets to hold my tools in my back room so I went with these as there were 12 and they have a countersunk hole and screws so you can mount them on the wall and the screws are flush and won't interfere with holding tools. They turned out to be much stronger than I expected. Check out the video I posted where the magnet bounces from almost 2 inches away. They are so strong that it is very difficult to separate them. However, this makes them great for storing whatever tools I put on them. I didn't actually have to use screws to attach them as I have an air handler in my back room that provides a large metal surface to just place the magnets on and then add tools to. It was so easy and works great. They have a metallic anti-corrosion finish, which is nice, but I noticed a few imperfections in the surface that created a tiny, sharp point that I felt sting as the magnets pressed my fingers very hard during the separation. There, so powerful, you have to be very careful not to get your fingers caught. Overall I am very happy with these magnets.
