FIRST4MAGNETS N42 Neodymium Pot Magnet for DIY, Engineering, Manufacturing, Hanging and Holding Applications - 60mm dia x 28mm tall x M8 thread - 139kg Pull

60mm diameter x 28mm tall with a M8 11mm deep threaded collar +/-0.1mm tolerance Each magnet can support 139kg vertically from the magnetic face when in flush contact with a mild steel surface of equal thickness Coated with three layers of nickel, copper and nickel to reduce corrosion and provide a smooth finish M8 threaded collar 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. An added advantage of pot magnets is that they are resistant to chipping or cracking following constant impact with a steel surface. These magnets come with a safe-handling warning; because they are so powerful they can be dangerous if not handled carefully. Box Contains One magnet
