Thread magnets are more and more used today, which including internal thread magnets and external thread magnets. The screw thread can not be made on magnets, 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.The whole magnet assembly have 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.
Under this category, we mainly introduce internal thread magnets or pot magnets with female thread. This permanent magnetic pot assembly are made by sticking a permanent magnet into a steel cup that with internal thread or female thread.Steel rings and hooks can be screwed into the threaded hole.We usually glue disc neodymium magnets into the steel cups.The steel cups can not only protect the disc NdFeB magnets but also ensure the neodymium disc magnets stronger magnetic force.Our neodymium internal thread pot magnets or internal thread NdFeB pot magnets are all made from standard property neo rare earth magnets, the internal thread magnets have higher holding force than others.
