With these strong magnetic hooks, you can conveniently attach heavy objects to ferromagnetic surfaces. The magnetic hooks reveal their full adhesive force when attached to the underside of thick steel beams and the load pulls vertically downward. When attached to a wall, on the other hand, they can hold noticeably less weight (see FAQ about displacement force).
Please note: Carefully screw the hook into the threaded bushing as far as it will go.
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.
