I was assembling an IKEA bookshelf, and one of the most important steps to ensure safety is the installation of the L-bracket to secure the bookshelf to the wall. All the parts, including the bracket and the screw for attachment onto the shelf, are included (see below). To my disappointment, however, the long mounting screw for attachment to the wall is evidently missing. So now, I find myself unable to complete the project due to the missing mounting screws.
I don't think this is a special case for the bookshelf or for IKEA. Why don't furniture manufacturers include wall mounting screws in the package for convenience?
