### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Nice bolts.
  

*by N***R on Reviewed in the United States on March 15, 2022*

Although not stated,  these are stainless steel. Also, made in Taiwan and ungraded, which doesn't really matter for this application. The bolts are finished nicely enough and the threads seem well cut. I had no problem exchanging the rusted ones on my bike for these.
