Paint splinters to long dowels?

My husband is sent by hand, but in this part we really annoyed us. The paint chipped the net Schauben the screw and an anchor was apparently too long. When we had all bolted together, we noticed that the anchor with a small hill on the other side of the wood came out again and the paint in the place looks like taken. Obviously we've had bad luck, because the stool is evaluated otherwise positive everywhere. Disassembling I do not want especially since that has verspeilt by the defective plugs into each other so that it would come apart again by force. How do I continue advancing now, I have not yet considered ...
