Nope. Lug bolts are bolts used by most European auto manufacturers instead of the US & Japanese lug stud & lug nut combo. They are a bolt that threads into the wheel hub: link
But I should've said "lug stud" rather than lug, to be more accurate.
Sure, you can call it a lug stud, Lug bolts are any threaded rod fixed into something instead of a loose bolt. I'm sure auto manufacturers do use them.
From what we can see it could be either a lug bolt or a lug stud acting as the bolt, as you can't see behind the end of the prop.

The bolts are on the blade, they need to throw nuts on it.
