the worst is not when the screwdriver is fucked but the screw is. That is some huge pain in the ass
Torx doesn't get fucked though, compared to alan or philips
What about square drive… where does it fit in
That’s right, it goes in the square hole.
Robertson! Say his name!
I was saying it in Mercian for our southern neighbours
I'm not american so you wasted it anyways
Fun fact: There are plenty of times a screw that looks like a Philips head is also compatible with a square drive. I've mostly seen this on electrical outlets and Ikea furniture.
I don't know why Robertson/square drives aren't more common. They're stable and they resist stripping and rounding.
You mean Pozidriv?
That much of material is not much of material.
wait really? I would imagine those small corners would easily get flattened compared to something with deeper ridges like philips
Phillips strips way, way easier than Torx. Stripping generally happens when a screwdriver cams out, or pops out of the screw. Here are some excerpts from Wikipedia of Torx vs Phillips.
And Philips on the other hand:
I'm not sure about Allen. It doesn't cam out very much, but it does still strip a lot easier than Torx. Probably due to the smaller contact points.
Well said.
And with the hex/Allen, it's the small contact points as well as the smaller volume of material that needs to be deformed or removed before slippage can occur, as well as the angle of force on the contact point.
With a hex, the contact point and direction are such that the tool is effectively trying to scrape off material at an angle, and if/when it succeeds even a little bit, it's now much more prone to fail.
With a Torx, the contact area might still be small, but it's being applied to the lobe in a more perpendicular direction, so rather than a scraping failure, it's more of a force that is pushing directly against steel instead of scraping. Not that it can't fail, but the route to failure is significantly less likely.
Yeah, it was made with torque in mind (like, it's in the name lol). For smaller screws using an impact, you can expect to break the screw before you strip the torx on top. And by smaller I don't mean tiny, more like M4, M5
Maybe because different material? Obviously CrV steel won't get fucked like chinesium, no matter the shape.
