Interestingly, it was an accidental feature. The original patent application makes no mention of it, but 9 years later they added language about it camming out to the second patent application. en.wikipedia.org/wiki/Cam_out
They make bad screw heads but the drivers themselves are useful for so many random odd-jobs that you can basically be guaranteed to find a flathead that’ll fit your screw within a few seconds of searching near basically any tools
Because of that many cheaper companies use flats for their screws, though I almost never see it in anything bigger than the little ass plugs we use in doorknobs and electrical socket covers. Once you go bigger than those it’s usually a Phillips/flat combo, or torx if you’re spending some extra cash
Oh god yeah I still use flat screwdrivers on a daily basis, basically as levers
“Little ass plugs” are called “grub screws” btw 😂
In 30 years you’ll catch up and they’ll all be 2.5mm Allen screws. I do remember them being slotted, it was a massive pain to find a screwdriver that fitted!
If you’ve tried to do any large amount of work with slotted, you’ll know that it belongs in Mental Disorders. I’ll take Six-Lobe/Torx over phillips or slotted any day of the week.
Yea but fuck the security torx screws. Also hot take, but underrated screw goes to tri-wing/Y. They’d be great screws if they weren’t security screws as well.

Is that a hot take? Everyone I’ve ever mentioned them to who knows what they are immediately starts shit talking both them and Nintendo for making us buy a screwdriver for one set of devices in our lives
The worst one I ever came across was five lobe tamperproof on a Seagate external hdd. Couldn’t find any bits for it that didn’t have to be imported. Ended with a rather destructive disassembly
They can take more torque, don’t cam out when screwing and most importantly can’t be damaged easily by constantly using the screw, unlike Philips which fucks off after second attempt.
It looks like the tape will hold the arming hammer closed even if the chain manages to pull the pin out. The tape is clearly strong enough to hold a live grenade to a wall…
I don’t think I’ve ever heard that fastener called an Allen bolt, just the tool (Allen key). I’ve generally heard them called hex sockets heads. Maybe it’s a regional thing?
In Dutch they are called “inbus”, which apparently comes from the German name “Innensechskantschraube Bauer und Schaurte”, where Innensechskantschraube means inside six sided screw and Bauer und Schaurte is the company who patented the screw type.
That’s not true when working internationally, since it can have different names in different nations. In Italy is Brugola, in Germany Inbus and in other places it has other names. Everyone understands what a hex key is though
I hate slot screws because they are easy to slip out of, and the place that I find them the most is always outlet covers. Like… What the fuck? Why are you gonna put the most easy to slip out of screw next to the most dangerous to slip into hole?!
