I've only used Nismo's extended studs, which I suspect have the correct knurling or whatever it's called, but in any case what I've been doing to install them is:
1) Set the stud lightly in place
2) Stack a few inches worth of large washers over the stud to cover most of the length
3) Put a nut on the end (same thread as your lugnuts, but just buy a few cheap ones at a hardware store to bang on)
4) Tighten the nut with an air wrench, and it will suck the stud fully seated as it tightens.
5) Remove nut + washers (duh).
