Here is just one of the examples available, it's actually googles first
hit for "twisted client example":
http://twistedmatrix.com/projects/core/documentation/howto/tutorial/client.html

The function "finger" shows what is needed to start up a client.

you "import MyFactory from mymodule" and use it as shown in example. You
can do that anywhere in your app.

I'd say the ironic thing is that sockets are so often used in a
different way, imposing lots of unnecessary problems (apart from the
fact that this is a rtfm question) :). What twisted gives you for free
is a rock-stable way to do all networking asynchronous, which is no
trivial task to achieve using sockets (i.e. writing a twisted equivalent
from scratch). When you get used to it, it won't be harder to do simple
things, and way easier to do complex things. It's certainly worth the
effort.
