Nuts seemed good enough. But in the box I received there were 2 nuts of different sizes. The nut's body was the same size, but these two were threaded to make the hole bigger. They helped and sent a whole new box of replacements which helped. But when I went to install the last 2 I noticed that everything I had installed a month ago was already starting to rust. I live in Ohio, it was December but the roads have only been salted once this year.
