Hook magnet Ø 20 mm

Thread M4, strength approx. 13 kg
promptly deliverable


With these strong magnetic hooks, you can conveniently attach office and kitchen utensils, clothing, etc. to ferromagnetic surfaces. The full adhesive force of these magnetic hooks unfolds at the bottom side of thick steel beams, when the weight is applied downwards. When attached to a wall, they can hold noticeably less weight (see FAQ about shear force).

The answer to why you can arrange pot magnets only side by side can be found under 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 around 2 kg.
You can unscrew the hook from the pot. If you don't need the hook, you can use the similar and slightly cheaper pot magnets with screw socket.
