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 43/91'' x 3/19'' countersunk circular magnets provide an astonishing magnetic pull for such a 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. Also available with the north pole on the countersunk face.
