It comes with the bolts to bolt the quick release to the boss, but you'd usually get the hex screws to hold the steering wheel on when you buy a wheel.
We don't usually sell the coned hex steering wheel screws, but we do have a couple of sets kicking about the office here.
If you want them, just stick an order through for bucket seat mounting bolts and stick a comment in saying you'd like the steering wheel ones instead http://www.driftworks.com/catalog/products/bucket-seat-mounting-bolts.html
