A neodymium disc magnet housed with a steel shallow pot with a male threaded mounting stud is called external or male threaded neodymium pot magnet. The size of male threaded stud ranges from M3 to M10.
Type-C: external thread magnets, external thread pot magnets, pot magnets with the external thread, external thread neodymium magnets, strong external thread magnets, external screw thread holding magnet. Neodymium Magnet Embedded in Steel Pot with Threaded Neck Φ20mm
Thread pot magnets are more and more used today, which including internal thread pot magnets and external thread pot magnets. It is impossible to make a screw thread on a magnet, so thread magnets have to be made with help of other parts – that is the steel cups with the screw thread or steel pot with thread for the screw cap.The whole magnet assembly has more powerful magnetic strength than a naked magnet. The new formed magnetic system just threads magnets, also called as thread pot magnets which contain internal thread pot magnets and external thread pot magnets.
Features
These magnets have only one surface of magnetic attraction. This type of construction prevents further spread of magnetic field. Due to this, other items or machine parts in the vicinity of the pot magnets do not become magnetized.
These magnets have ability to retain their magnetic force indefinitely.
The magnetic force of these magnets are only affected by the increased temperature and external magnetic force.
