Rubber Coated Mounting Magnets With Internal Threaded Bushing
The rubber-coated mounting magnets with internal(female) threaded stem/bushing(shorted as internal thread rubber-coated mounting magnets) offer magnetic bases for waterproof magnetic ceiling hooks and rustproof holding magnets for outdoor use. All the internal thread rubber-coated mounting magnets are made with N35 neodymium material, which produces the strongest strength. For different applications, you can screw different threaded hooks and lifting rings into the internal thread post.
This rubber-coated neodymium pot magnet can be also made with an internal(female) threaded stud, external(male) threaded stem, and threaded screw socket on one non-magnetic side. Because of the soft rubber coated waterproof magnets, scratches are avoided on the surface of contacted objects. You can use the rubberized magnetic system as a magnetic base on cars and fridges for mounting or holding objects.
Rare earth samarium cobalt magnets, shorted as SmCo rectangular magnet, are a type of powerful permanent magnet made from the basic elements samarium and cobalt and other metal rare earth materials by mixing, melting, grinding, pressing and sintering. They come in various sizes and shapes, like disc,bar, ring, arc,block, etc.,. Similar to neodymium strong magnets, they belong to the rare earth magnet category, and tcan be classified as SmCo5 and Sm2Co17 according the composition ratios of samarium and cobalt.
