Help -- attach headboard to metal frame?
I bought a beautiful Pottery Barn metal headboard off Craigslist. It is like new. I want to attach to a metal bed frame. Pictured below is the hardware that came with it. Four of everything except one washer, which I am sure I can replace. Here's my conundrum. What order does everything go in and which end of the bolt faces the wall? This is not exactly a decorating question, but thought someone here might know.
All the hardware is shown sitting on the back of my mouse pad. Ignore that gold seal in the middle. So, WWYD?
