This magnet in a steel pot has a countersunk hole 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 counterbored hole.
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)
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
