see my review of sku1262556: These magnets are quite strong.Therefore when letting them loose in close vicinity of each other, the impact speed can be large causing them to break. This because the material is very brittle. So when using a screw to fix them, take care to tighten the screw gently. The holding force to a steel plate is around 700-800 gram.

Great magnets and the countersunk holes make it really easy to bolt them to something. Just be careful not to overtighten or the magnet will crack.
