Countersunk magnets are extremely popular neodymium disc magnets with a countersunk central hole to allow the magnet to be easily fastened into place for a temporary or permanent fitting. All our neodymium countersunk magnets are available with a countersink on the north face of the magnet or on the south face. Remember if you are using two countersunk magnets together, like poles repel and opposite poles attract. 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 countersunk face. If you want to use two magnets for repelling each other in a repelling, damping or shock absorbing application then you should purchase two identically polarised magnets.
