It is now impossible to imagine industry, timber construction and hobby craftsmen without pot magnets, also known as flat grippers. Pot magnets with a cylindrical bore are ideal for attaching a metal object to the wall or ceiling. The magnet can be attached with any screw, whether Allen screw or Torx screw. The head of the screw disappears completely into the centre hole of the magnet. The magnetic shielding of the steel pot around the magnet increases the magnetic force in the "open" direction.
