Produced with bore and countersunkExcello Pot magnets with bore / countersunk produced with strong neodymium magnet. Magnet is safely enclosed in the metal pot and the cylinder bore facilitates the mounting. This pot magnet is primarily used as professional holding function within the industrial area.
By using a countersunk head screw, users can easily screw the pot magnet onto places where they want to hang, for example, tools, small iron parts etc. The openness of the countersunk can be changed to match the size of screw head.
Countersunk magnets are available with either pole on the magnetic face so that they can be used as a pair to attract or repel. If you are using two magnets to attract you need to make sure the opposite poles are facing each other as identical poles will repel! This magnet in a steel pot has a countersunk borehole and can be fastened with a countersunk screw. Ø48mm Neodymium Flat Pot Magnets with Counterbore
