are give the name of rare earth neodymium(NdFeB) countersunk block(rectangular) magnets,the countersunk hole make the block magnets mountable.The neodymium countersunk block magnets can be screwed onto other surface,and used as magnetic holders.
The magnetized direction of powerful neodymium(NdFeB) countersunk block magnets generally axially magnetized and magnetized through-hole direction, other magnetization direction is determined by the required working face.
