Strong Ferrite Pot Magnets(magnetic bases) with inner thread holes! Made from the strong Neodymium Iron Boron magnets, punching mild steel housing and plastic spacer that all are assemble to be a set of pot magnets and then they are magnetized to be magnetic before shipment, these pot magnets offer substantially more holding and gripping power than ferrite pot magnets.

This kind of configuration and design will keep the magnetic flux more concentrated and the products more powerful. These pot magnets are perfect for use in tooling and fixturing and holding field. Contact Us Now
