A compact magnet system consisting of a steel shell with high permeability and a countersunk magnet is a countersunk pot magnet (also known screw - on pot magnet). The cup magnets with countersunk hole are easy to install. The countersunk cup magnet has a single attraction surface, and the magnetic lines of force are more concentrated. The bolt with a countersunk head is flush with or below the top of the magnet, which optimizes the suction surface of the countersunk pot magnets. Neodymium, ferrite, and smco magnets are all available for our countersunk pot magnets. Countersunk pot(cup) magnets are very suitable for closing mechanisms using magnets, in which the screw heads must be hidden, such as cabinet doors, drawers, door locks and door fixing devices.
