unable to connect the baskets do to not having nuts to secure them together

I like this product although I think its a little overpriced. However, I was excited to get it and went to assemble it last night but due to not having nuts am unable to connect the three baskets together to hang where I want to hang it. There is no way the baskets will stay together with just the screws they provided. I am not sure how to put it together without a nut to secure it. I'm not sure if nuts were suppose to be provided or not but I defiantly did not have any in my package.
