Description

Top seller: More than 650 000 sold!
This magnet in a steel pot has a countersunk hole and can be fastened with a countersunk screw. It is especially popular with our customers in the mechanical engineering and construction industry, in electrical engineering, the advertising industry and precision technologies. But it is also often used in private households.

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.

The following screws fit into the CSN-40, for example:

  • Slotted countersunk wood screws: DIN 97 (5 mm)
  • Cross recessed countersunk flat head screws (machine screw): ISO 7046-2 M5 (5 mm)
  • Hexalobular socket countersunk flat head screws (machine screw): ISO 14581 M5 (5 mm)
  • Hexagon socket countersunk flat head screws (machine screw): ISO 10642 M5 (5 mm)

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 and neodymium magnets. You can find additional fascinating information on our FAQ page about pot magnet features.

PDF data sheet
The graph shows the maximum adhesive force in kg (y axis) at various distances in mm (x axis) between pot magnet and counterpart (steel plate).
Example: At a 2 mm distance between pot magnet and steel plate the maximum adhesive force is still around 10 kg.
The answer to why you can arrange pot magnets only side by side can be found under our FAQ.
