FIRST4MAGNETS Rubber Coated Pot Magnet for DIY, Engineering, Manufacturing, Hanging and Holding Applications - 22mm dia x 10mm thick x M5 thread hole - 3.8kg Pull - Pack of 80

Pack of 80 22mm diameter x 10mm tall with a M5 threaded hole +/-0.1mm tolerance Each magnet can support 3.8kg vertically from the magnetic face when in flush contact with a mild steel surface of equal thickness Rubber-coated to increase friction and prevent marking other contact surfaces M5 threaded hole for assembly 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. Because these magnets have a rubber-coating they are ideal for using to attract fragile or easily marked surfaces, the rubber coating increases friction, softens impacts and prevents marking. An added advantage of pot magnets is that they are resistant to chipping or cracking following constant impact with a steel surface.
