Self drilling screws ...

Into what ever you want screw:-)

Anything? These look like they have extra-long reamer sections,
compared to the threaded length, so AFAIR these particular ones are
for putting steel corrugated sheets onto thin folded steel purlins.

They'll probably work into wood, but there's not much length of thread
to hold.
