ELI5: Why do manufacturers use Allen wrench screws for self assembled furniture instead of Phillips or flathead?

They’re just easier. On the assumption that you’re provided the correct Allen wrench, hex screws are less likely to strip, you get free leverage from the shape of the tool. The tools themselves are super cheap to make, so compared to the hassle of dealing with customers so are mess up their cross head screws, it’s probably cheaper too.
