• 22mm diameter x 10mm tall with a M5 threaded hole
• Each magnet can support 3.8kg vertically from the magnetic face when in flush contact with a mild steel surface of equal thickness
• +/-0.1mm tolerance
• Rubber-coated to increase friction and prevent marking other contact surfaces
• M5 threaded hole for assembly

Neodymium pot magnets are made of a powerful N42 Neodymium magnet sunken into a steel shell meaning that the north pole is on the center 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.
