Cup magnets have the simplest structure,but they are the most commonly used magnet assembly.The cup magnets with countersunk hole in the center of magnetic surface are known as countersunk cup magnets.With the countersunk hole which suitable for screw,you can mount the countersunk cup magnets easily to other non-magnetic object. Neodymium countersunk magnets and ceramic countersunk magnets are often used to assembly countersunk cup magnets,neodymium countersunk cup magnets are used in heavy duty situation.
