Like our other types of pot magnets, countersunk pot magnets are covered with a steel "pot/cap" that enhances the adhesive force when in direct contact with an iron surface.
Countersunk pot magnets make it easy to screw the magnets to a wall or surface with a countersunk screw so that the screw does not protrude. Some of the things countersunk pot magnets can be used for are:
Magnetic door holder
Magnetic fishing
Magnetic furniture assembly
Organising tools on a tool wall
Hanging ceiling tiles for e.g. mobile exhibitions
Pot magnets are very powerful due to their steel cap. But be aware that the strength is calculated with a direct pull. If the pot magnet is placed on a vertical surface (e.g. a whiteboard), the pot magnet will hold 10-15% of its rated strength before sliding down or tipping off. Therefore, you should check whether the pot magnet needs to hold something vertically or horizontally and choose the magnet strength accordingly. To prevent the pot magnet from sliding down, you can increase friction by using a rubber cap. You can find a link to these below.
