These neodymium pot magnets have a metric internal thread and can be screwed together with objects having a suitable external thread. The rubber coating protects delicate surfaces from scratches and at the same time increases the load capacity in shear direction.
The rubber protects the magnet from occasional moisture and splashes. Permanent outdoor use, however, may lead to the formation of rust. Our ferrite pot magnets, on the other hand, are rust-proof.
Compared to standard pot magnets without a rubber coating, these rubberised pot magnets are thinner and more discreet. There is a steel plate under the rubber coating with 12 embedded magnets. They are arranged alternately with north and south pole facing up. As a result, you will be able to combine these pot magnets with each other. But please be careful, because once two of these pot magnets are fully joined, it will be very difficult to separate them again.
Please note: This pot magnet has a full-length thread, requiring extra care when threading screws, hooks and the like to prevent damage to the rubber coating.
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.
