Screw-on metal bases

The metal plates are counterparts/bases for magnets. For example, if you want to attach a hook magnet to the wall, you can screw on a metal base and then attach the hook magnet. Metal bases are available in several sizes, so it is possible to find one that fits most magnets. It is recommended to choose a metal base that is a few millimeters larger than the magnet so that the magnet makes full contact with the metal base. The metal bases can be screwed on with countersunk screws.
Please note that the metal plates are NOT magnetic and are not suitable for outdoor use as they can rust.
