This magnet in a steel pot has a countersunk hole and can be fastened with a countersunk screw. This is one of our top sellers, thanks to its versatility: It is used in the shopfitting industry as well as in plastics engineering, the automotive industry and mechanical engineering and construction.
The following screws fit into the CSN-20, for example:
- Slotted countersunk wood screws: DIN 97 (3.5 mm)
- Cross recessed countersunk flat head screws (machine screw): ISO 7046-2 M3 (3 mm)
- Hexalobular socket countersunk flat head screws (machine screw): ISO 14581 M3 (3 mm)
- Hexagon socket countersunk flat head screws (machine screw): ISO 10642 M3 (3 mm)
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 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
