What's it called?

>>2946241 (OP)
Phoenix pzsl or combo or wiha ph-s or whatever your favourite brand calls it

It’s not iso/din so it doesn’t matter

>>2946244
Cool, thanks

>>2946241 (OP)
It's for Electricians to get the torque of a slot with the centeri n g of a Phillips.


They've been emphasizing torque specs lately so 5 ugga duggas isn't actually good enough

>designed for tradies to strip the screws in my house just that little bit more

based?

>>2947235
Arguably it's so they can actually torque them down as screws are made of fucking cheese

Why do they make anything besides Torx or Robertson at this point?

I mean I guess flathead has machining applications but other than that everything could be Torx

>>2947241
industry standards die a glacially long hard death especially when construction code and insurance. im surprised the nec goons even allowed adding the phillips head cross on screws on ul shit before the year 2100

>>2947243
Is it really code?
Or is it just the typical American thing where they have been making the same shit for 100 years and just can't be bothered to change?

In reality there shouldn't be a need for Trox, it makes sense for structural purposes but electrical doesn't need that much torque.
I guess an issue is lots of screws aren't high quality like another anon mentioned, I've noticed it too.

>>2947246
>aren't high quality
but they are
they are suppposed to be conductive and corrosion proof, not hold a car suspension

>>2947256
They're also supposed to be able to be driven. Phillips head is ass and cams out if you're not basically standing on the driver. Never had a Torx cam out once

>>2947278
>Never had a Torx cam out once
I was driving some long ass Spax brand Torx screws to put a frame together and literally half the box cammed out. That was using the bit that came with the box. I ended up having to drill pilot holes.

I've also seen tiny ones cam out when taking apart old hard drives to harvest the magnets. That was likely because they were just frozen in place after years and nothing would get them out. Had to use a rotary tool to grind the heads off.

>>2946241 (OP)
last time I tried to buy one of those bits (when I could find one) they wanted an absurd amount of money for them. I ended up buying an electricians screwdriver with bits stored in the handle just for that one bit. the whole set was half the price of one bit.

>>2947246
>but electrical doesn't need that much torque.
Maybe not on the components themselves, but there's plenty of screwing boxes to studs and stuff like that in electrical.

I think a big part of Phillips sticking around is down to how convenient it is, one #2 driver will do 95% of the screws you encounter, even if sometimes it's not a perfect fit. Torx on the other hand has a million sizes and you're fucked if you don't have the exact right one. Also it seems to be harder to manufacture given how many times I've had drivers not quite fit right in screws. I've never dealt with Robertson since I'm not a leaf but wouldn't it have the same problem hex does where the bit gets stuck in the screw half the time? Or does the geometry somehow avoid that?

>>2947391
I was just gonna say, it's way easier to get them in sets. A ton of Klein drivers and bit sets come with them.

>>2947391
That one came from chinkland; it actually cost me nothing as it came in the box with some other stuff

>>2947241
Because neither can be used at an angle like with a ball end hex. When there’s no space to align the driver well, hex is best

>>2947394
Like 14 inch pounds on a reside tial outlet, 20 on a Commercial. 250 on a main breaker

>>2947394
You can literally stick a Phillips driver in a torx screw and if it's the right size it'll work just as well
Inb4 "security" torx

>>2947394
>Torx on the other hand has a million sizes and you're fucked if you don't have the exact right one
my gripe with this is fucking t20. make the goddamn screws either t15 or t25. no inbetween shit
you cant tell 20 from 25 at a glance and 20 will kinda drive 25 but strip out when you really start cranking

>>2947278
>Phillips head is ass and cams out if you're not basically standing on the driver
yea but that is an american exclusive issue kek.
In europe we use PZ/S, pozidrive slotted in the style of OPs driver. Grounding screws that clamp ring terminals are often torx

they were invented for those universal screws that just suck in every way
The concept is wild to me.

You can usuall find them on industrial electric parts and the screws are designed that you can use any screwdriver.
Quite the oposite of torx or safety torx which started out to lock people out of messing with parts they should leave alone

>I was driving some long ass Spax brand Torx screws to put a frame together and literally half the box cammed out. That was using the bit that came with the box. I ended up having to drill pilot holes.

You didn't align the bit with the screw, you canted your driver heavily, using the slack between the bit and the screw, which then creates a cam-out force.
It is only noticable when you cant hard, the bit is sloppy, and when a shitton of torque is being applied.

Torx was created to transfer the maximum amount of torque, nothing else.

>>2947927
Not what I did. I could feel when the bit was properly seated in the screwhead. Shit drove just fine and only started camming out at the last inch or so. A box of Spax Phillips heads of the same length drove without issue into the same type of wood. I'd get Robertson if I could but I don't live in Canada.

>>2947928
That's a funny thing to say when slotted exists

>>2947293
Had the same experience with Spax stainless. On the other hand, the cheap ass coated steel torx from a decade ago just pretzle the bits if I use too much torque.

Maybe stainless is just kinda shit? Or Spax.

Nah robertsons get stuck too. Still, I'd rather the bit get stuck than have the screw strip because I looked at it funny.
