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.

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.

You can unscrew the hook from the pot.
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 around 2 kg.
