Comment on acceptable screws
CaptainPedantic@lemmy.world 7 months ago
Philips screws are awful. They strip if you look at them wrong. Flatheads should only be used on thumbscrews just in case you need a little extra torque from a screwdriver.
Torx and Hex are excellent.
Torx gang unite.
We had our 20 y/o deck repaired and stained last year. I was chatting with the overseer about what he was going to do and the topic of screws came up; he said he was going to use Torx, and only ever used Torx anymore - I just about cheered.
I’d been losing hope in humanity lately, but little signs of sanity like this, professionals finally getting rid of the hell-bits that are Phillips heads, lifts my heart and gives me hope.
These days, all but the cheapest outdoor-grade screws in the US are torx, generally with a bit thrown into the box that, while cheap, should work fine for a few boxes’ worth.
Freaking awesome. Better and better. We’ve finally fixed the screw heads, and pretty much also computer connectors (and small device chargers!) with USB-C. Just in time for the end of the world via total ecological collapse.
Great times.
I’ve heard that was more of a European thing, but the only two serious contenders are Pozidriv vs Torx for screws (and hex vs Allen for bolts).
I just checked my local hardware store’s website, and out of the 176 kinds of 4/4.5mm screw boxes in their inventory, 74 are Torx, 55 are Pozidriv, and 38 are Phillips (ew).
Either Torx or Pozidriv is fine when used properly, however most DIYers don’t understand the difference between PZ and PH and end up stripping their heads. Also it’s much harder to use the wrong-sized bit with Torx than PZ.
So yeah, Torx wins in just about every category and other heads only get manufactured to appease old people and penny-pinchers.
That’s one of my issues with Pozi - it can be hard to see the markings, and not everyone has great eyesight. I mostly object to Phillips-related screws because there are so many variations that mostly look the same and require a table to differentiate. And none have the torque-transfer performance of Torx. Plus, you can use a hex head in a Torx bit in an emergency and you don’t much care about either the bit or the head.
Flatheads should only be used on thumbscrews just in case you need a little extra torque from a screwdriver.
The only other legitimate use I’ve seen for flatheads is on wooden boats, where you’ll be gooping the head up with tar for waterproofing. Since you’ll eventually have to scrape it back off again to get to the fastener, you want a simple geometry that’s easy to clean.

Square (Robertson) drives are actually great too. Better than Hex/Allen, but Torx is the most reliable, and the most German. Phillips can take a long walk off a short pier.
I do wish Robertson heads were more common. They’re almost as tough as torx, but tapered to stick on the tip of the tool, which is so convenient.
The ones with bumps in the middle can go fuck themselves
Square is nice too but square/Phillips is a good damn lie. Because the Philips side of it doesn’t work well enough so it is still just a square but with extra slots
I feel like spanner would be the best for not having shit getting stripped.

I work on electronics and woodworking and Phillips are the utter worst of both of them. The thread lock in computers makes them easy to strip when unscrewing. The resistance of driving them into wood makes them guaranteed to strip when screwing. Fuck them.

The big issue I see with people driving Phillips screws is that they don’t use a large enough driver size. Computer screws for example are Phillips #2 and I’ve never had an issue with them stripping.

I use the correct driver, I’ll go through my kit to find the best fitting bit. It simply comes down to the fact they are designed to strip to avoid “catastrophic failure”. Plus the fact that companies use intentionally cheap, soft screws, to make repair and service harder. Cough cough zinc screws on a $10,000 iMac (steel screws would have cost 25 cents for 10, zinc like 5 cents for 10, fucking ridiculous).

I read that the thing about them being designed to strip to prevent worse failure is just a myth. Or at least they weren’t originally designed to. It said that the original patent never contained any feature for that. Wouldn’t surprise me though if modern companies do use screws designed to strip to prevent disassembly/repair.

I always figured it was intentional but for the other reason: screws soft enough that overtightening can't damage/crack the multi-thousand dollar components, the screw head cores out first.

It’s also a design flaw that it’s so easy to use the wrong sized driver and it will sorta work. It might be annoying that you have to have a set of different star drive or hex drive bits, but you’re less likely to strip them.

Could be that it’s not a Philips but a JIS. I didn’t even know that JIS existed until a couple years ago. The shape is close enough to Philips to mostly work but make it super easy to strip.

Maybe I’m just being lucky but I’ve never experienced screws stripping anymore since I’ve started getting better tools for myself.
And in woodworking it can also help to pre-drill a hole using your smallest drill, before screwing a screw in. This also prevents the wood from cracking. I’ve also seen wood screws that have some lubrication pre-applied.

The problem is, when working with electronics, you can have a great screwdriver but it won’t help if the screws in the device are very cheap (and probably partially stripped already from someone opening it previously).

I swear I’ve had stuff with stripped screws right from the store.
NaoPb@eviltoast.org 7 months ago
I’ll be honest that I’ve never really experienced problems like that before. I’ve had cheap screws and partially stripped screws. But so far I’ve always been able to open them with the right screwdriver.
But I believe you when you say you did and maybe you have a lot more experience than I do so I’ll respect your opinion.
