This pot magnet with countersunk hole has a thicker steel pot and hence, a higher adhesive force than conventional pot magnets. It can be fastened with an M8 countersunk screw. Please refer to the technical data for the exact dimensions. This extra-strong countersunk pot magnet is frequently used in industry, mechanical engineering, exhibition stand construction, furniture manufacturing and the retail sector.
Neodymium magnets are brittle and can break under excessive application of force. Therefore, we recommend a maximum tightening torque of 2 Nm when fastening this magnet.
Please note: The full adhesive force is achieved when the ferromagnetic counterpart is smooth and of sufficient thickness and when the pot magnet makes direct and full flush contact. Pot magnets already lose much of their adhesive force at a distance of only half a millimetre to the ferromagnetic surface. This characteristic is more pronounced in pot magnets than in other ferrite magnets and neodymium magnets. You can find additional fascinating information on our FAQ page about pot magnet features.
