FIRST4MAGNETS Neodymium Clamping Magnet with M4 Eyebolt for Hanging, Holding or Displaying Items - 20mm Diameter x 34mm High - 16.5kg Pull - Pack of 10

Pack of 10 20mm diameter x 34mm high +/-0.1mm tolerance The internal diameter of the eyebolt is 8mm and is 26mm from the tip of its thread to top Each magnet can support a steel weight of up to 18.3kg vertically from the magnetic face when in flush contact with a mild steel surface of equal thickness Removable eyebolt with M4 thread Coated with three layers of nickel, copper and nickel to reduce corrosion and provide a smooth finish These are the second smallest clamping magnets in our range but still provide an astonishing 18.3kg clamping force for their size. These Neodymium magnets are 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 these magnets is that they are resistant to chipping or cracking following constant impact with a steel surface. However, they are not suitable for underwater applications.
