A ferrite disc magnet housed in a cup or pot shape ferromagnetic iron shell that with a female threaded bushing is shorted as internal(female) threaded ferrite pot magnets. The internal thread steel cup not only ensures the safety of the ferrite disc magnet from damage but also strengthens the magnetic force. Due to the use of steel shells, only one magnetic surface can be used for working, and the other surface is steel and metal iron. Because of the internal thread bushing, the steel hook and eyelet can be screwed on the internal thread ferrite cup magnet.
All ferrite pot magnets with internal（female）threaded stem are assembled with anisotropic ferrite disc magnets. Our ferrite cup magnets may be even stronger! The steel cup can be made with chrome-plated, nickel-plated, zinc coated, and paint coated, even rubber coated. The below table shows the standard models of internally threaded ferrite pot magnets.
