There are also those gold "pin" type ends you can put on them if you'd prefer to terminate with something other than bare wire. I have a set of wires made up that terminate with these that are handy to have around as they pretty much work with anything, good for testing as they always will fit anything other than old style screw terminals. They will work in cheap spring terminals, the binding posts you have without the spade/banana capability, as well as, of course full, 5 way binding posts. I've also had some of these that are of a flat cross section that Radio Shack sells that work pretty well but can be a bit "bendy". Never had a problem with them though.
