This strong pot magnet has a stem with an external screw thread. You can slide the stem, for instance, through a hole and fasten it with a nut. The magnet is often used in the plastics and automotive industries (rail and bus manufacturing), by architects and in graphics.
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.
