Nice, but using Torx heads for the case is completely unnecessary. If the internals are fine using PH0 heads then the the case can use PH heads too.
I recently found out after wanting to do a quick repair on my (very cheap, Asda's own brand) toaster that it uses Torx security bits to prevent people from accessing the internals! Buying a set of quality bits is more expensive than just buying a new toaster... It boggles the mind.
Nobody should use Philips when Torx will do. Philips is useful when you have weak parts that you want to avoid over-tightening. But otherwise, Torx is less prone to stripping and requires less downward pressure, making repairs easier.
How hard are you torquing a screw into a plastic case? Really? If you're stripping a PH screw head it's almost always a case of using the wrong sized driver
I opened up a 2017 or 18 Dell Inspiron last week to replace the hard disk with an SSD for someone. Of the 4 screws holding down the hard drive caddy, 1 stripped the head. The other three used almost no force to remove. This last one had to be drilled out just to remove the drive.
If the computer had used Torx screws in place, I'd never have had the issue since the force required wouldn't have stripped the head while a PH head had cammed the driver requiring the excess use of a drill.
Are you maybe confusing "Torx security" bits for plain Torx bits? Torx security bits have a hole punched through the center that is indeed a pain in the butt. Standard Torx bits on the other hand are pleasant to work with and extremely easy to come by (heck they give them out for free with most construction screw boxes).
A builder picking up a pack of screws won't buy something he doesn't have a screwdriver for, and a basic toolbox will only have screwdrivers for the most common screw heads - giving these things quite a bit of inertia.
So an American might consider Torx a widely used screw that everyone has a driver for. Whereas a Brit might rank Torx as an obscure security screw, like pentalobe.
They are common place enough now that I think they are fine. That wasn't always true but these days torx is widely available even at generic hardware stores (hell in Thailand I bought a set of torx drivers at a 7-11).
You are correct when we're talking about using Torx for things that need to be torqued fairly highly, but in this case I disagree.
The fact that so many companies use Torx bits means that a lot of people have them handy now, but still, it's more faff than a PH/PZ bit, where almost anything with a thin flat edge can be used to turn it.
Torx are designed for high torque applications. Whenever they are used for low torque applications it is for "security" (read: we don't want you messing with this) purposes. I'd argue that a case does not need to be torqued that high (and if you do you probably risk cracking the case).
IMHO fixings tend to be selected prioritizing a manufacturing point of view rather than how easy they are to disassemble (with the exception of specific security screws). PH/PZ screws can get cammed by a misaligned tool or unskilled operator in assembly, requiring a rework or writing off the chassis. This is less likely to happen with Torx.
Torx bits good enough to not strip your stuff are like 6 dollars for a set.
If the toaster is "totaled" over 6 dollars, that's because it was built to be one step above disposable and no one should reward them by buying it in the first place.
Frankly I wish philips head screws would just die off. They're so easy to strip, it's frequently hard to identify the right size bit to use (the wrong size will work until it doesn't), etc. If they all got replaced with torx or robertson heads tomorrow I'd be very happy.
