Countersunk magnets are really popular because of their versatility. They are great for us around the home for mending and fixing, for making furniture or magnetic latches on doors, drawers and gates. These 15mm diameter countersunk magnets are made from high grade neodymium and are supplied with a central countersunk hole for fixing in place. Every magnet is available with either pole on the magnetic face. Magnets with opposite poles on the countersunk face can be used to attract two surfaces or two opposing countersunk magnets with the same pole on the countersunk face can be used to create a damping or repelling effect.
