Here is another one I just saw yesterday. Usually when I need to space a device out to fush it with the wall (when the opening is cut too big) I will make little springs by curling some scrap wire around the end of my needle nose. Late yesterday on a service call I pulled a receptacle and the previous electrician had used a bit of small diameter rubber hose (like automotive fuel line) and just cut off the proper length and slid it over the screw.
Can't wait to try that one.
