Countersunk ferrite pot magnets

These countersunk pot magnets are fitted with a ferrite magnet. Ferrite magnets are much weaker than neodymium magnets, but they are cheaper and can be used in outdors and in damp environments if you don't mind that the steel pot will rust.
Countersunk pot magnets are easy to mount on a wall or surface using a countersunk screw. Some use cases for countersunk ferrite pot magnets are:

  • Magnetic door holder
  • Magnetic assesmbling of furniture
  • Organizing tools on a tool wall
  • Hanging ceiling panels for art exhibitions
Countersunk ferrite 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.
