Description

Top seller: More than 3 100 000 sold!
This magnet in a steel pot has a countersunk borehole and can be fastened with a countersunk screw. Our customers use thousands of them in the lighting industry, shopfitting, in mechanical engineering and construction, as well as metal construction. It is also very popular for home use. We also carry this pot magnet with cylindrical borehole.

The following screws fit into the CSN-25, for example:

  • Slotted countersunk wood screw: DIN 97 (5 mm)
  • Cross recessed countersunk flat head screws (machine screw): ISO 7046-2 M5 (5 mm)
  • Countersunk torx screws/hexalobular socket (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 1 mm distance between pot magnet and steel plate the maximum adhesive force is still 4 kg.
The answer to why you can arrange pot magnets only side by side can be found under our FAQ.
