20x10x3mm is popular size for block neodymium with one countersunk mounting hole. The countersunk hole accepts an M3 screw, which screws the countersunk neodymium magnets onto other surface and use them to hold magnets. Neodymium countersunk block magnets 20x10x3mm with a grade of N35 have to pull force of 4.3kg, the stronger force can be got from the grade of N52. Block countersunk neodymium magnets 20x10x3mm are usually delivered with N and S poles, nickel is the common coating for most of the applications.
