High-performance countersunk Neodymium (N42) magnet, available with either pole on the countersunk face. Compact but incredibly strong.
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. Because of their superb strength these 25mm x 5mm countersunk circular magnets are also used in recovery and retrieval applications, providing 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. Also available with the north pole on the countersunk face.
We have used the magnets for a safety system on a commercial vehicle, They have worked very well.
