The bolts do not look like stainless - they look like low quality steel bolts plated with zinc.  The manufacturing looks poor.
IMO, they are the 13 cent variety, not the $1.13 variety.  Same for the nuts. They are the 5 cent variety, not the 55 cent variety.
There is low quality stainless but I have never seen that used in nuts and bolts.  Threaded pieces are normally 18-8 or better and have better machining.

 Whar are the tip-offs in the picture that they ared ow quality?
 

Having had experience with high quality bolts would be a start. Then look at the thread - that is visibly of poor quality, as is the shaping of the head of the bolt. Overall, looks like cheap Chinese shit!
