The Problem: Leftover/Missing Hardware
There is a well-known saying about leftover parts. "You know a job was done right when you have pieces left over." Of course, this is nonsense. Leftover hardware is a sign that something wasn't put together properly, and the saying itself is just a poor excuse for an incomplete job. On the other end of the spectrum, there is the issue of not enough hardware, which has just as many associated problems.
