Mark,

Can you provide more details on what I'm seeing here? I can't tell what
they are or what they hold.


That's the nut and washer on the end of an anchor bolt lag-threaded into the
leg. A 1 1/4" pocket drilled into (not through) the back of the front apron
has enough room to thread the washer and nut on the machine thread end.
There's also a 1/2" tenon on the end of the board, dry fit into a mortise on
the leg.
