^^^THIS^^^ I have done it countless times. I will use 6 point or 12 point, English or metric. Whatever doesn't fit but can be hammered over the lock. Beat it on, impact or cheater bar them loose. Chisels are bad, they tend to work the stud loose. Hit it wrong and you can bend the stud, stretch it, loose the interference fit to the flange and have a nut stuck to the stud and the stud spinning in the flange. Now you have big issues! There are special sockets, I find the hammer a socket over the bolt works better then the special tools. I have even installed (and torqued no less) locking lugnuts with the hammer a socket in place trick. No reason to get any more complicated then that.
