I went out to our warehouse to measure the opening in the link for you on the Curt Safety Chain with S-Hooks # C80031. The inner measurement is 0.52 inches at the weld and the links are 0.66 inches on the inside so your 1/2 inch bolt will fit. I measured with a digital caliper so it is precise and have attached a photo to assist.

The rating listed for a single chain, like the Curt #C80031 at 5,000 pounds of capacity, will double when two are used. So the #C80031 used as a pair will mean you would have 10,000 pounds of capacity. With that said, I am not a huge fan of the…
