NdFeB countersunk magnets have a central hole which is countersunk to allow the magnet to be fastened in place using an ordinary countersunk screw.
These magnets are all available with either a north pole on the countersunk face or a south pole on the countersunk face.
If you want to use two magnets together to attract each other, you should select one magnet with a north pole and one magnet with a south pole on the countersink.
If you want to use two magnets for repelling each other in a repelling, damping or shock absorbing application then you should purchase 2 identically polarised magnets.
