I used some of these when installing some floating shelves and I'm impressed. They are quite solid once installed. I'm surprised though that they claim to be able to hold 20kg! Has anyone actually put 20kg of weight on one of these?

According to the box, the nylon ones can take 20kg and the zinc ones can take 10kg.
