The bracket might be somewhat limiting because of stress concentrations, bending forces, etc. A quick calculation will show that a 5/8" rod, with a cross section of about 0.3 square inches, will take a tremendous load. Even marginal structural steels should be over 50,000 psi tensile strength, so that would result in at least 15,000 lb on each side of the d-ring. If I remember correctly, mine were rated about 6,000 lb WLL and 18,000 lb strength, so there's some margin, but the rating might be actually based on one side of the ring.
When we welded these on, we went through a lot wire. My guess is there is at least 3 square inches of weld connection compared to the much smaller ring cross section.
My trailer has a net capacity of 5500 lbs and I never actually load it over about 4000 lbs (truck limitations). Since I always use all 8 hold downs if I have a heavy load, I'm pretty comfortable with the capacity. You guys with big trailers and big equipment may have more to worry about.
