As a matter of interest, when and why did cars change from using threaded studs
fastened into the hub with the wheel fastened to the hub by nuts, to the modern
practice of using bolts (machine screws?) into threaded holes in the hub?


No they're definitely screws, of some kind or other if they have to be
screwed in. Maybe calling them all "bolts" as with cylinder head "bolts"
is some kind of affectation among car mechanics.


My astra wheel nuts /bolts are not screws.

If you've got nuts, then they're bolts obviously.

That's the definition of a bolt; something with a thread on the end onto which is
screwed a nut.

The OP is talking about screws which you screw into the hub with no nuts involved.
