Pot magnet with external thread, Ø20 mm.

Strong magnet with external thread (M4).

Neodymium magnet with a steel pot surrounding it (enhances the magnetism) and thread to screw the magnet directly into the wall or plug like a screw. You can also attach the magnet with a nut. 

Two of these magnets with external thread cannot be used facing each other, as the poles face the same way on all the magnets and will repel each other.

The strength is measured in direct pull on steel. The more space between magnet and magnetic surface, the weaker the magnetism. 

NOTE! The pot magnet is not made of stainless steel, which is why we recommend indoor use only.

We do not recommend using pot magnets on magnetic glass boards, as the edges of the steel pot can scratch the glass board.
