Rare Earth Round Hole Holding Magnets
Neodymium is the strongest magnetic material and the metal casing on these Pot type magnets cleverly deflects the field to the base for increased power and holding ability. Round Hole holding magnets are designed with nut or bolt style of attachment in mind. For heavy duty industrial or commercial applications, where attachment needs to be stronger than a mere screw, Round hole Pot magnets are ideal and much more difficult to dislodge. They can accommodate a nut and bolt style attachment that won't come loose during vibration, physical pressure or other duress. Once a hole has been drilled in the material you want to become magnetic, which can include wood, aluminium, acrylic, and stainless steel, a nut, and bolt will secure the holding magnet in place. This allows these materials to attach to metallic surfaces in a non-penetrative way and without the need for nails, rivets or glue. Steel washers are recommended when bolts are used for attaching a magnet to help prevent the magnet loosening and being displaced.
