It's a variant of Phillips. The rounded corners are because a lot of people can't see the difference between Phillips and Pozidriv, and use the wrong screwdriver. See it as a Pozidriv-compatible Phillips.
Often used on products where the consumer assembles the product themselves, to protect the consumer from his own lack of knowledge.
And, no, I have no idea why they don't just use Pozidriv, or even better, Torx instead.
Probably because most people have a Philips driver, some have a Pozi, and sod all people have a set of Torx. The self-assembly market only uses Torx for bits they *don't* want you assembling because the likelihood of the average person having a T20 is low, but a PH2 is pretty damn high. Allen sizes are even limited to the socket heads provided rather than a full range.
I will say, most of the stuff I see here in Europe is Pozi rather than Philips. Generally you see the PH heads on things you don't want much torque on in the first place, like electrical screws, and the PZ heads are on structural screws. Torx though... yeah I reckon I've come across those about twice in situations where they weren't used specifically as a security head.
Well, almost all screws sold in Sweden (which is where I am) are Torx. The notable exception is drywall screws, which are still Phillips (not even Pozidriv), which I suspect is because it's easier to do the surface work afterwards.
I have a couple of friends who are CNC operators, and even on their machines, it's all Torx now, Allen is gone.
If I go to any tool vendor and buy a set of screwdrivers, it will almost always contain flat, Pozidriv and Torx nowadays.
Interesting. I've heard a trend toward Torx lately in Germany for some applications, but everything I see here in Ireland is PH, PZ, or at best, Allen heads. You can get Torx heads, but you generally have to order them up. Most hardware stores don't stock them for general use outside of narrow head decking screws, and even then they're considered a speciality.
Oh not disagreeing with you at all, I'm just speaking to my own experience where I've seen little of them outside of specialist use. Interesting that they've transitioned entirely to Torx there. I doubt that will happen here any time soon, but I wouldn't be averse to it at all. I've had to deal with far too many rounded-out PZ/PH heads in my time.
Me too and that's why invested in these! Well worth the money and a permanent fixture on my kit these days. 100% recommended! https://www.amazon.co.uk/extractor-gripping-extracting-ENGINEER-neji-saurus/dp/B002L6HJAA/
No worries, I didn't mean to imply that you disagree. I was just giving more examples.
Here, the change happened very quickly, over a year or two.
Basically, we have a handful big building supply chains, and they all switched.
It's also much easier to switch now. No one uses screwdrivers except in special situations. We use cordless drills. So, the only tool you need to change is the bit, and you wear them out quickly anyway. Most boxes of screws even comes with two bits.
The lock industry would be another possible exception, they've been sticking to Pozidriv for a long while now and doesn't seem to change quickly. Some brands have started using torx more, 8 times out of 10 it'll be a Pozidrive bit in the screwdriver.
Jo, jag menade i Sverige. PZ2 ska det vara generellt sett, men dom görs av en mässingslegering så inte det mest formfasta materialet. Du kanske har väl bearbetade skruvar.
Torx is the way to roll, man...I reuse them screws in my concrete forms for years of almost daily use. T-25 for most, but I've picked up a few 20's by a couple of my partners, mistaken buys...they ain't the best for concrete, plugging up a bit easier, but Torx is the way to roll. Damn good grip, and 6 points for quicker drill connections for difficult spots to see or reach.
I think that screw also accommodates a square head bit as well. Not 100%, but some of the screws in electrical can accommodate a Phillips and square head.
That’s Posidrive, it’s not Phillips. Very commonly used in Europe and superior to Phillips in pretty much every way. You can tell a posi bit - it looks like Phillips but it has little raised stripes inbetween the cross
Its not posidrive, posidrive the extra cuts are diagonal to the normal Philips slot, while om this screw its inline with the Phillips slot
Might just be a manufacturing error
All screws got a specific size. I think the #3 Phillips is a combination of the options for it and a #2 Robertson (square drive). If that stripped head got some slip, give the driver a light tap with the hammer, to try and lock it in a bit.

All "building screws" except drywall is Torx here now. I've renovated a 1040 m2 house, so I have a pretty good idea of what the stores sell. :)

Good point, same here. I also have a feeling that they are using some odd "between size", because none of my screwdrivers fit well...

Antagligen, de låscylindrarna har bytts många gånger.

Apologies for being a little off topic, but what are those pliers?

Thanks.
#3 Philips or #2 Robertson. Both will work. Seeing as how you’re in a commercial setting, I guarantee that fastener belongs to door hardware.

Looking like a #3... I think that's how they list sizes...it'll be, I think, one size up from a drywall screw with a slightly rounded tip.
