Well-engineered hardware is definitely interesting, but unfortunately this article is rather lackluster. I'm not even talking about the many typos, but absurd claims like the suggestion that the use of Torx screws "Protects Dyson from counterfeit" really should not make it into an article by somebody who claims that they are "engineers, like you".

Their try at explaining the physics involved also does not quite convey they feeling that they understood what is happening and how.

When reviewing and optimizing BOM costs, Torx screws are almost 2x the cost of a standard Phillips which helps to distinguish knockoffs. Folks who counterfeit items are looking to maximize profit and will always go for the cheapest items and not many people look at screws to see if they're different. Lots of threads out there about this. Even with this said, and as we pointed out, it’s not the main reason Dyson chose Torx screws—the primary reason would have been for proper fastening to ensure a tight assembly that wouldn’t come loose.
