Take off another one & head to your local auto parts. Just about all of them will have a little rack with a bunch of lug sticking out of it. Find the one that fits your lug nut & you're done. Make sure the one you buy has the same seat as the ones on the bike. If you don't you could crack your rim. I'm 8000 miles from home right now or I would give you the exact size & threads.
