To enjoy 22kg holding force specified with caution

First: Since I get relatively easy pried from my whiteboard the magnets, I thought, that it withstands the very most half the stated 22kg tension.
So I once made a test and hung one of the magnets to a horizontal oriented unpainted steel fork my forklift. Then a construction site bucket with a thin handle hooked (so it does not come to a lateral tension) and then very carefully reingestellt calibrated weights kg for kg.
I was surprised that the hook has solved so only at 20kg (+ Bucket weight).
But unfortunately then also not the magnet has become detached from the forklift fork, special of the cap in which he is apparently glued. Hence the points deduction.
Otherwise, the magnets are beautiful chrome (or nickel-plated?) And make a quality impression.
If you want quite suitable to hang a keychain or something else easier, for example. On a refrigerator door or a white wall.
