Just like our other types of pot magnets, the countersunk pot magnets have a steel "pot/cap" that increases the adhesive force when in direct contact with an iron surface.
Countersunk pot magnets make it easy to mount the magnet with a countersunk screw to a wall or surface. Some of the use cases for countersunk pot magnets are:
Magnetic door holder
Magnetic assesmbling of furniture
Organizing tools on a tool wall
Hanging ceiling panels for art exhibitions
Countersunk pot magnets have a very strong magnetic pull force due to their steel pot/cap. But be aware that the strength is calculated for 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 the stated strength before it slides down or tips off. Therefore, you should check whether the pot magnet needs to hold something vertically or horizontally and choose the magnetic strength accordingly.
