Ideal for furniture fixings, hanging artwork and keeping doors and drawers closed, counter-bored magnets have a central hole which allows them to be fixed to non-magnetic surfaces with a screw. Our 25mm x 20mm counter-bored circular magnets are the largest in our range and provide an astonishing 22kg magnetic pull. Counter-bored magnets with opposite poles on the counter-bored face can be used to attract two surfaces or two opposing counter-bored magnets with the same pole on the counter-bored face can be used to create a damping, shock absorbing or repelling effect. These magnets come with a safe-handling warning; because they are so powerful they can be dangerous if not handled carefully. Also available with the north pole on the counter-bored face.
