I've had a bed frame stored in a closet for years and have lost the fasteners with which to assemble it. It's an Ikea Heimdal frame; this item is discontinued and they no longer carry the fasteners needed to put the frame together.
The fasteners can be seen in the assembly instructions here, parts #100585 and #100013.

One part is basically just a shank, the other an elongated head. They are unlike anything I've seen at the hardware store, so I would like to know what these pieces are called and where I can find replacements. I hope they are not unique to Ikea.
