Hi everyone - first post, please pardon mistakes. I attempted posting 3 pictures, but can't tell if uploading worked. First picture shows side pieces of roommate's just-acquired, disassembled bedframe. Second picture shows edge of side piece, where the long screws go into the side from the headboard, and the circular depressions where the matching metal inserts should go; each insert should have 2 holes in it, so that a screw can pass through the insert. The insert holds the screw and provides more strength than just the wood of the side piece. Third picture shows measurement of the insert holes, which are 1 3/8 inches in diameter. What are these inserts called?? I need to order them, so that the frame doesn't fall apart. Any suggestions welcome!

I can't remember where I obtained these screws. They are blue with dual level threads, See attachment. Jim /*
