I’d like a bookcase headboard for my bed, but can’t find one I care for. I’d like to make my own using the kind of fastening hardware that comes with flat pack furniture at Ikea or Target (as opposed to fine carpentry joints).

I have a good understanding of the tools and hardware involved (auger and spade bits, cam screws and connectors); I’m looking for more information about placement and grades of bolts and fasteners to determine the best structural assembly. What are some good resources to tap?

Any online resource would be especially helpful: DIY websites or forums, sites with flat pack/RTA specifications, PDFs of assembly directions for similar pieces of furniture, etc?
To “I Need More Cowbell”:
We’re talking about the same thing: putting furniture together with hardware as opposed to carpentry joints such as biscuit joints, dovetails, butterflies. Flat pack furniture is anything that can be taken apart. It can be made of solid wood, or of laminated particle board. It can be well planned and sturdy, or poorly structured.
