Product Description 20mm diameter x 30.5mm high including the hook or 14mm excluding the hook The internal diameter of the hook is 7mm 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 hook with M4 thread Professional gloss-white finish These small clamping magnets are capable of supporting an incredible 18.3kg in a vertical position and 3.7kg in a shear position when clamped directly onto a steel surface, despite being just 20mm in diameter. The neodymium magnet is 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 magnet 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. The professional and discreet finish makes these magnets ideal for hanging point of sale (POS) and retail displays. Box Contains 1 x 20mm dia magnet(s)
