Elise uses quite normal M12x1.5 (fine pitch metric) bolts with tapered seat. Regular off-the-shelf stuff everywhere.
Bolt length standard is 25mm (threaded portion), but... If you look inside the threaded holes on the hub you'll see that it's actually using only 2/3 of the total space available.
Look at the back of the hub with the wheels and bolts in place and you'll see that they don't reach all the way to the back of the hub.
I found that with 30mm bolts they screw in all the way, so they are flush at the back of the hub, so they use all available thread. Always a good thing IMHO...
