Sort of. Except where the cap end (in the picture in that thread) is clearly is made to accept a 8mm hex, mine is completely smooth inside. I think you are right though about just finger-tightening it. It only takes 4 in-lbs (0.7 Nm?) of pressure. And it does not hold the crank on. It only holds the bearings in place. I guess. I'm far from an expert on this. I just can't figure out why both the Park Tools book and FSA's website seem to be wrong.
Maybe it is nothing more than tightening it with my fingers and going on my way.

Weird. The FSA tech specs are rubbish. One
drawing has the preload bolt looking like it takes an hex key and calls it an M18 or M12 preload bolt another
drawing looks like what you describe and calls it an M18 crankbolt. And yet another
drawing calls it an M18 crankbolt but again it's looking like it takes a hex key.

this site The FSA Gossamer MegaExo has no link to a manual just says to post questions at the right. I'd post a question if I were you.
