This listing includes two pieces of neodymium cup magnets and same number of screws. These cup magnets are made of super strong neodymium magnets encased inside of the steel cups, which causes both north and south poles of the magnet to concentrate on the same side, i.e. the opening side, so to triples the holding power to 88 pounds each. The countersunk holes on the magnets are for number 10 flat head screws which are already included in the package for your convenience. Notes: Keep these away from pacemakers and children under 5 years old.
