Hard to tell from the picture, but is the nut tapered like a lug nut? If it is, it could go into a lug nut hole on the wheel. I bought an aftermarket spare tire holder; it has a strap, not a washer. I don't know what the factory set up looked like, I have an under bed mount which I am not going to use. I'm not even sure it is all there.
