Countersunk Neodymium Magnets are made of a powerful Disc Neodymium magnet sunken in to a stainless steel shell meaning that the north pole is on the centre of the magnetic face and the south pole is on the outer edge around it. The stainless steel pot increases the adhesive force of the magnets giving them an incredible hold for their size and also increases their resistance to corrosion. An added advantage of pot magnets is that they are resistant to chipping or cracking following constant impact with a steel surface. These magnets are counter-bored on the magnetic face and can be fixed to a surface with a screw, pot magnets are also available with countersinks and threaded studs.
Strong neodymium magnets with countersunk and counterbore holes:
Tapered / countersunk holes fit a standard flat head screw.
Countebore holes fit a pan head screw, nut, or bolt head.
Magnets may be purchased in matching pairs for a magnet to magnet attachment.

Ideal for furniture fixings, hanging artwork and keeping doors and drawers closed, countersunk magnets have a central hole which allows them to be fixed to non-magnetic surfaces with a screw. Our NEO countersunk circular magnets provide an astonishing magnetic pull for a relatively small magnet. Countersunk 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, shock absorbing or repelling effect.
