Have you seen the way they connect their wires? They just twist them
together and put a plastic cap over the bare wires!

They are called wire nuts, and contain a threaded metal insert. Sort of an
inverse of a self tapping screw. I understand the hesitance, but they don't
seem to be a problem

I fixed a Weller TCP iron a couple of weeks back that was running cold. A 'wire
nut' inside was loose and a connection to the element had become iffy.
