Screw pin D-ring shackles will work. I've seen USA made screw pin shackles distort under load without failure. (Don't know if that applies to the typical emerging country products.) I recommend selecting a screw pin or bolt shackle, not a pin shackle that just uses a cotter pin keeper. Stainless steel may be a good option if sized correctly.

I prefer them to hooks for directly connecting chains to the anchor points. S hooks have been known to jump off. I loop the shackle over the hitch anchor loop and position the pin through the proper length safety chain link. I always orient the screw pin thread to be on the lower part. A bit of Vaseline or grease on the threads keeps things from seizing.
A hook will easily fit into a D-ring shackle if that is what you want to do.
