Neodymium Magnet NdFeB, Square, Countersunk

A magnet that has the strongest magnetic force with a flat bolt hole being open, and is it is easy to mount.
[Features]
· Strong magnet composed mainly of Nd (neodym / neodymium), Fe (iron) and B (boron).
· Compared to the anisotropic ferrite magnet, it has approx. 8 times stronger energy product, and its mechanical strength is also superior.
· As the anisotropic magnet itself is easy to rust, it is usually coated with nickel plating on the surface.
[Usage]
· By using the magnificent magnetic power, it can be used for industrial products, magnetic separation machines, machine tool, industrial robots, MRI, etc.
· Ideal for speakers and computer hard disks.
