The polarity of these magnets is the same for all magnets in the pack. If you intend to mount them with screws so they sit flush in pairs, this won't work. It's not entirely clear why these magnets are countersunk when one side needs to be flipped to fit flush. Also, several of the magnets in the packaging were broken or chipped. Won't be getting them again for my woodworking projects in the future.
