those are "welded steel rings".. as I recall, the 1/4" diameter ones
(the diameter of the rod they're made of) have a load rating of few
hundred pounds.
Yes, they'll deform under load, but what you're really concerned with is
tension failure of the metal, and that's way above the deformation load.
Yes, they're not typically x-rayed or inspected as far as weld quality
goes. So you'd maybe want to double them up?
