It is an insert with threads to accept the bolt. A wrench will not work on any of this.
The bolt head looks like this pic.
Well, I did figure out / understand the "socket-head cap screw" part, but assumed there was a standard hex-nut on the backside ... and that is what I was suggesting could be held with a wrench.
I'm not 100% sure of the correct name of those insert-nuts, but I call them "riv-nuts
" or "nut-serts". They are commonly used to hold mirrors on the side of a door, luggage-racks on a trunk lid, etc.
I gotta say that I have never seen them used on a cross-member. That is usually nut-and-bolt or rivet territory.
