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

In: 1849

Answer 1

Here in UK, they provide the actual Allen wrench as well. Presumably, if they used screws, they’d be expected to provide screwdrivers instead. This would be disadvantageous because: some member of the British public would find a way to stab themselves with it; you get a lot less torque with a screwdriver; screwdrivers have a tendency to jump out and/or scrape surfaces; screwdrivers need a handle of some sort, so are more expensive
