Ikea are really missing 1:1 prints of screws and parts I shouldn't mix. See e.g.:

Yeah, ikea doesn't do the 1:1 (or at least I haven't seen it) but they tend to use unmistakable parts. Like each of the metric cylinder head machine screws are different enough in aspect ratio it's easy (for me) to tell them apart. But I'm good at flatpack assembly (likely due to lego obsession growing up). I can see how that might be confusing for some.
Contrast that with the Anderson door I build last month. Didn't have any scale indication, really small diagrams, lots of nearly interchangeable fasteners, and way too wordy.
