Here you will find our range of industrial pot magnets with a central counterbored hole for fixing in place. All our counterbored magnets are magnetic on the counterbored face.
Pot magnets are made from a powerful magnet sunken in to a steel shell meaning that the north pole is on the centre of the magnetic face and the south pole is on the outer edge around it. The steel pot increases the adhesive force of the magnets giving them an incredible hold for their size.
