Quick release axles are hollow so the quick release skewers can go through the axle. The hub shell is not threaded because the hub never makes contact with the axle- the hub contacts the bearings, the bearings contact the cones and the cones contact the axle. The reason your new axle needs to be the same thread pitch as the old one is so the old cones will thread onto it. Also, be warned that you might have trouble getting both cones off the old axle. They have a tendency to become frozen and the only way to loosen one is by torque-ing against the other, but then there's no way to get the second one off unless you have a bench vise with a special widget for gripping threaded things without damaging the threads, and even then it might require some penetrant and a few hours to soak. Although, come to think of it- if you're willing to throw away the old quick release axle, just put it in a bench vise and smash it until it ovalizes, which should give you enough leverage to get the second cone off.

Edit: Come to think of it, they sell bolt-on skewers for quick release hubs, but I have no idea if they work or not.
