This deep pot magnet with a diameter of 16 mm and internal thread M4 has a remarkable adhesive force of approx. 9 kg. This high magnetic adhesive force is achieved because the forces of the neodymium magnet inside the steel cylinder are focused toward the holding surface. This deep pot holding magnet can be securely mounted thanks to the internal thread.
What applies to pot magnets, also holds true for deep pot magnets: 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.
