"This idea was used for centuries to pump water, dig holes, and for pressing the shit out of grapes to make some wine" Wow, you got me stunned right there!
Man, for millenia we've taken insane efforts to get wasted! Alchemists would never research destillation, boiling points, measuring temperature, discover antiseptic properties of concentrated ethanol etc, if it wasn't for getting drunk even faster!
"Why Are There so Many Types of Screws?!" I haven't read all 3829 comments, so my point may have already been made by someone else. This article is about the different types of SCREW HEAD. It hardly touches on the far more important property of a screw, bolt or nut, namely, the SCREW THREAD.
@@fillinman1 - The United States is unlikely to abandon US Customary units, but we use metric units as well, wherever there is a reason to. The US adopted the metric system in 1866 and since then has contributed to its development.
Love it. As a Canadian, I never knew that Robertson screws were pretty much unique to here now. I mean, I did know that their inventor was Canadian, but I just assumed that being a superior product to Phillips screws (and infinitely better than slot-type screws), they would have found worldwide acceptance. They're just...normal here, available everywhere, used by pretty much every contractor at least some of the time. Of the three main types of screw heads, they're by far my favourite (it's crazy how something over a hundred years old can be so high quality even today). Also, apparently, P. L. Robertson had a really good reason why he was unwilling to license his screws to Ford. He had entered such an agreement with an English licensee company whose parent company intentionally drove the licensee into bankruptcy so that they could buy the English rights at a reduced price from the trustee. Robertson spent a fortune getting the rights back, and from that point on, he refused to license his design to anyone else, which made Ford look elsewhere. That he went with the VASTLY inferior Phillips shows how desperate he was to have the supply chain under his control (which is weird...if the product is worth it, why not just sign a contract requiring Robertson to supply him with X amount of screws a year, for Y amount of years, at Z price, thus ensuring that he would always have access to what he needed?). As good as Robertson screws are however, they take 2nd place overall to Torx in my opinion, which are really quite wonderful to use. I've been using Torx wood screws for a few years now on various projects, and if I have the option, I'll always choose them.
Yea I own a Pentalobe, couple very small Philips and a ducking Y000 bit for certain iPhone repairs. They’re definitely cheap and worth it for the repair but that’s one of the things I wish Apple would give up. However I will say the Y000 was one of the most secure feeling screws ever.
"It was used in Apple's first PC to make it harder for the average guy" So... Apple's been making dodgy, non-standard things from the moment they started? Neat
He just described how torx screws are great at preventing cam-out and tool/head damage. Their reasons for making them may be dodgy, but the screws are on point, mate
@@totesjokin5354 while I agree that positive outcomes should be commended instead of berated whenever applicable, the circumstances really make it obvious that Apple's primary purpose was to screw over customers, and the good mechanical property of the screw head has been incidental before everything else.
CDgonePotatoes “purpose was to screw over customers”.. nice pun there, guy lol. But no, I completely agree. It probably wasn’t OPs intention, but his choice of words made it sound like Apple’s screws themselves were garbage, and I just wanted to voice my worthless two cents.
"If all these nuts are driving you crazy, you might just be a squirrel" Wait, is this a lead-in? "And being a worldly squirrel, you'd probably want to learn" Yup
well...its still useless if only....ehh....3 (?) Countries around the world still using imperial measurement units. The modern World shifted to metric a long time ago.
@@hetsmiecht1029 Statement rejected ;) Where its needed, digital infrastructure, science,.... The USA uses metric system. USA is like a person who feels special for using a Mac, but doesnt realize that the base components, vital hardware, is already Microsoft xD
This stands up, in my opinion, as one of the greatest works of film on the internet. Every second of this video is just about perfect, and I rewatch it often!
Thought I would learn that all those different types of screws have actually a purpose and are not just to piss me off. But you made my day by confirming that it is indeed just to piss me off! Have a nice day.
In germany theres basically 4 types of screw heads: Hex, Nut, Plus, and Minus. Plus, Minus, and Hex are pretty much what you expect, hex screws usually being used in manufacturing, and nut screws have heads shaped like nuts so you can use the tool youd usually use for nuts to apply them instead of a screwdriver. And from there, the differences are based on what the screw is supposed to be used for, for example, there are your run of the mill screws, theres cutting screws used on sheet metal to cut their own thread, theres ones with elongated, thin shafts made so that you can apply pull to them, which is useful in applications with a lot of pressure present thats trying to force parts apart, etc.
I still remember our shop teacher saying, "now remember that Robertson is a square head" and some keen wit saying something like, "that'll be easy, Robert is a squarehead too"
There are benefits to knowing both. There are also negative aspects. When in the hospital they put my weight in the kg box as 188 and converted it to 413 pounds. They were to put the 188 in the pounds box so the guy in pharmacy sent them to see if I was really 413 pounds because that would affect how much medicine he would give me. There was also an aircraft that was only filled half full because they mixed up the imperial and the metric. The plane ran out of full half way into the trip and crashed. BUT if you know and understand both then there are things I like about both.
In my work in the US, I also have to deal with both. Inches can kiss my ass, especially when dealing with fractions and decimals. Sixteenths can already kiss my ass, and then you have measurement tools that want to tell you that something is 1-21/200. Fuck you, just give me the metric measurement already.
Gosh darn it dude. Your channel is a freaking roller coaster. From being so informative and captivating, and then putting together such a humorous intro. It is truly a juggernaut of keeping things entertaining and practical just as the label says. I still remember the frozen chicken test about yeeting it into a jet turbine. The small bits of humor really does make the knowledge that underlines it all memorable. Even without any practical experience with any of the things you describe, it still feels awesome to understand the mechanisms behind the most mind boggling engineering feats in such a simplistic way that a simpleton like me can comprehend. Keep it coming man. I'll always be looking forward to the next one.
I remember starting an engineering degree (I was not smart enough to finish it) and watching a student who was putting a wing nut on an exceedingly long bolt slowly turn the thing through every thread. I had to show him how to hit the thing to get it spinning so you weren’t there for several hours.
Some Torx sizes are even cheaper than the Phillips sizes they replaced. They've been available at hardware stores and Walmart and dollar stores for years.
Engineers think they have it rough. Try being an aircraft mechanic. I have an entire drawer in my already-bloated toolbox dedicated entirely to driver bits. Also, pro-tip: If you apply valve-grinding compound to your bit, it causes cam-out to happen at a much higher torque. Combined with significant down-force, you can break loose even the most stubborn screws. Important in aviation, as all our hardware is engineered with much tighter tolerances, and we heavily employ the use of self-locking nuts, threadlocker, and other sealing and safety methods. Still, Phillips and its kin completely suck. If I had a dollar for every rounded screw I've had to cut out with a drill, I could quit being a mechanic, and retire to a tropical island. Torx aren't much better either. Having to torque a full cockpit window's worth of the things completely destroys a good bit. Best hope your company stocks good ones, because you'll be replacing them often.
@@TimLF Hex head bolts. They can tolerate extreme torques without slipping when using an appropriately sized 12-point socket. The drawback is that they can't be used in areas where aerodynamic smoothness is necessary. Which is everywhere on a plane. For flat screw heads, my favorite is probably a tie between spanner-heads, and torqset. Through, better than phillips, torqsets can only handle about 30 in/lbs before camming out dry. And the lower-quality brands of bit will literally break at around that torque.
spanner looks completely illogical and the first thing you read when you look it up is them breaking off. torqset doesn't look like it works nearly as well as a lot of other geometries nor does it look like it has the ability to be driven safely at an angle.
I don't recall the Apple // series computers having odd screws. The Macintosh introduced in 1984, on the other hand...Did. Steve Jobs did not want the tinkerers who played with cards and the like on the Apple //'s to play with the innards of the Macintosh.
l love this channel, but he indeed does not have practical knowledge, re standard vs metric, metric is super prone to being misthreaded resulting in stripping, its way less common in the larger stepper slope of a standard screw. But yeah, agreed "we" here in the US are wrong about many other things!
@@jonathanfoltz9713 metric screws work just fine, nobody is going to bend backwards to fit the imperial system because its such a pain even if there are any advantages
@moo iFixIt came to be because of Apple's anti-consumer repair stance on their products. Their sets are designed to include every bit, especially Apple's, that is until they decide to invent a new one. And the fact that Apple tried to pass a law that would essentially make it so that iFixit wouldn't even be able to exist is straight up disgusting. So, bottom line is, if it were for Apple, you wouldn't even have you "modest" iFixit set.
Then there's Android letting their OS be open source which causes a lot of problems for compatibility of apps available. Google made it open source so companies could put it on any phone they make. It was a middle finger to Apple.
@@scotthenrie5674 Who the hell is talking about Android? We were discussing Apple's hardware side. As far as I know, Android doesn't even do hardware. Stop basing all you opinions of fanboyism. Also, open source is the opposite of a problem. And for your information, OSX and iOS are both based on UNIX which is indeed open source.
@@scotthenrie5674 I don't support companies, and if you do, you are a fool, as they don't have your interests in mind. I support myself and which option is better for myself. But again, we are deviating from the topic at hand.
I have worked in general contracting and home building in Florida for many years and now finally I believe my RU-vid recommended gets what I like to watch a 3 am
I had a minor existential crisis when I went into a hardware store in Japan and couldn't find a Robertson screw. They had been so ubiquitous when I was growing up in Canada that I couldn't even fathom a world without them. It was as if I had travelled to some nether dimension where the people where actually lizards wearing monkey costumes...
I already knew all of this info (MSc Eng, QUB), but I'm so happy that this Irish guy is making really informative videos in a way a non engineer can understand (having had many friends and relatives ask some of these questions). Thanks bud. I've just subbed after 3 videos (that's a compliment, cos I'm subbed to maybe 6 channels). Edit - the sly Irish-style digs at imperial measurements also helped.... 🤭
@@kensmith5694 actually its even stronger in the heavy duty industry. Only very big companies can afford the full spec software for one make, and companies often have multiple makes. Basic software you cant even do full diagnostics
Fuck corporations. Here in Canada there is a law project coming against "preprogrammed obsoletism", forcing companies to provide spare parts, but I doubt they'll overcome the shit-eating powerful lobbyists.
I was hoping this video would cover more screw types, like Tri-wing, Torq-set and Torx-plus. Or explain what's the difference between a Philips and a Parker, and would finally explain what's the idea behind the Pozidriv (PZ)! I still have so many questions now....
@@minecraftfirefighter if its broken and can be repaired, you cant open it yourself to repair it, go to apple and they'll say its irreparable despite countless shops doing the same work job. Making you pay 400+ for a new phone. Louis Rossman.
@@applecore4720 If you subscribe to Louis Rossman you already know about things like iFixit. Savvy consumers know they (or their local shop) can fix things without OEM extortion. But most consumers buy fashion, not tech, and they basically don't mind having an excuse to buy even newer fashion. Until they finally can't afford to keep up with fashion.
I live in the states, but when I went up to Canada I was standing on a relative’s porch, and then for some reason I looked at one of the screws and went “wait, that’s not right. What on earth? What is this?!” I had never really seen Robertson screws before, except perhaps in electronics, but even that is a rarity. It genuinely shocked me, in large part because my toolbox wasn’t Canadian-Compatible now...
It really is the best screw. Great torque, doesn't slip, doesn't fall off the bit, easier to insert than a torx or philips. I'm shocked because my whole life up until today I thought it was the standard outside of Canada too, but wow apparently nobody's heard of it.
Woodworker in Colorado checking in to say that we use square head screws basically every time we need a screw. Kreg even uses them in their excellent Pocket Hole Jigs.
Personally, most English ("Freedom") units are varying degrees of superior to Metric ones, with few exceptions. One of the best examples of this is Fahrenheit's absolute and complete superiority to Celsius. In other cases, though, like mile vs. kilometer, there is no difference.
@@caffeinatedinsanity2324 I've only ever had a torx driver break once, and that once time it sheered in half, thepoint themselves did not break. The force is evenly distributed oer all of the points so there is very little risk of anything breaking.
torx screws are the devil, so are people who sell torx screws and people who sell torx screw drivers. you want to know how to improve a torx screw? easy, weld a hex nut onto the head. hex screws are the only screw the world needs. everything else is just proprietary bullshit.
In Canada, Robertson bits are square on the face but trapezoidal in their fit. I’ve been told it makes for a better torque surface area. Also been told the American version is simply a square with four parallel sides for fit.
I moved to NZ in 2011 & was confused by the square-drive screws used here. Now I've learned that they are Robertson & also that they are the best, numero-uno, fab & fantastic. Just one more thing that makes me love being a Kiwi in training.
A house we bought had a TV mount attached to the wall when we moved in and it was bolted into the studs with security hex bolts with the little pin in the middle. The angle grinder immediately came out.
