Description

This strong magnetic hook has a black powder-coating. The coating is applied through an electrostatic process and is free of harmful substances. Thanks to its colour, the magnetic hook is inconspicuous when mounted on dark surfaces.

If you would like to attach the hook magnet to a ferromagnetic surface on a wall, please take note of the displacement force indicated above. This specification corresponds to the maximum weight the magnetic hook can support on the wall under optimal conditions.

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.

Additional features and tips

You can unscrew the hook from the pot.

Why these hook magnets can only be arranged sideways is explained in our FAQ.

The graph shows the maximum adhesive force in kg (y axis) at various distances in mm (x axis) between magnet and counterpart (steel plate).

Example: At a 1 mm distance between magnet and steel plate the maximum adhesive force is still approximately 4 kg.

The structure of pot magnets

Pot magnets have a neodymium or ferrite magnet built into a steel pot. When it comes into direct contact with a surface, its force will be focused on the holding surface as a result. This increases the adhesive force of the magnet. For more information, please refer to our FAQ page on the characteristics of pot magnets.
