Undersænket powermagnet, Ring 15x4 mm. boardmarker mix Either with knuckle grease orThis round neodymium magnet has a countersunk screw hole (M3). The countersunk hole ensure that the screw will sit flush when fully screwed on the magnet plate. In addition, it ensures the screw will not hinder the magnets level of magnetism. But when a screw head sticks up and is not flush with the magnetic surface, it will create distance making the magnetic force weaker towards a counterpart for the magnet (direct contact = full magnetic power).
