N42 Neodymium Pot Magnet for Arts, Crafts, Model Making, DIY, Hobbies, Office, and Home - 25mm dia x 8mm thick x 5.5mm c/bore - 20kg Pull

Neodymium pot magnets are made of a powerful neodymium 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. An added advantage of pot magnets is that they are resistant to chipping or cracking following constant impact with a steel surface. These magnets are countersunk on the magnetic face and can be fixed to a surface with a 5mm diameter screw, pot magnets are also available with countersunk holes and threaded studs.
