Thanks, I've got a couple.
Nice to note that the studs are harder metal than then wheel nuts.

Not sure I understand this. Surely the hubs had to accomodate both wheel types as well.

I agree, I thought the steel wheels had a totally different wheel nut.

The nut will never bottom out on the hub, IIRC the correct torque is 120 ft/lb, which the hub and stud are easily able to cope with.
The spare is mounted to a flimsy bit of tin, by comparison. The longer nuts are designed to bottom out, preventing pulling the studs through the lighter material. The spare does not require the same amount of torque as the road wheels.

Fair enough if the wheel is an alloy, but my D1 has steel wheels and nuts like Slunnie posted. No bottoming out on those. Interesting...

Are these hollow?

It's only the threads that aren't full length with the wheel nuts, you can just use a tap to extend the thread further so they can be used on the spare wheel carrier. With a little care you can run the tap down just far enough to make little dimple in the chrome shell so you can ID them.
