FYI, they're called "Plate Bolts"
I was in the same boat as you and never had any luck.
I instead bought a couple of Eye Bolts, Washers, and Nuts and it worked perfectly. You just need to get the right size that will fit "long ways" and then turn 1/4 turn and they'll stay put after tightening them up.
Like one of these.
