• +/-0.1mm (0.004 in.) tolerance.
• Each magnet has its south pole on the counter-bored face.
• Each magnet can support 21.4kg (47.19lbs) pull vertically from the magnetic face when in flush contact with a mild steel surface of equal thickness.
• Coated with three layers of nickel, copper and nickel to reduce corrosion and provide a smooth finish.

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 (0.98 in.) x 20mm (0.79 in.) counter-bored circular magnets are the largest in our range and provide an astonishing 21.4kg (47.19lbs) 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.
