D-rings in another name for them. Though some call those weld-on loops, D-rings, so it's all who you talk to.
I strongly suggest that you get the screw pin design. Pulling/placing a cotter pin is difficult in most situations. A screw pin design is simple enough. Make sure you hand tighten then back off 1/4 turn, otherwise you'll be using a hammer and screwdriver to try to get it to turn.
