“Peak innovation” yeah, that’s why endurance racing teams are literally “prototyping” engine tech. F1 is a little confusing when you start thinking about what the intent of certain rules are
just like the rotary engine and the turban engine race cars of the past as soon as they won a race they got banned not because they where wasteful on fuel or dangerous that was just an excuse to tell the public, But because they worked better and lasted longer than the bigger companies that funded the events and angered them. You can those companies for not allowing us to have cars that run on other kinds of engines, sadly the only recent fuel powered engine in History to be mass produced and sold to the public was the wanker rotary and it is the ONLY none reciprocating piston engine to win at le mans.
for some reason I always think 8 for hex at first. Something to do with the X maybe. It cost me points on university challenge when i thought hexapods must mean spiders :(
With NASCAR's introduction last year of the single nut, we saw a lot of evolution, growth. Wheels were flying off everywhere. They still don't have it down perfect getting those drive pins seated. The F1 guys do it so fast you have to watch in slow motion to see them actually do it where it looks like they get em lined up perfectly every time.
To be fair, f1 has a person who’s only job is to use the wheel gun for one wheel while NASCAR has to get the whole stop done with 5 people and one guy is fueling the car and one is usually operating the jack.
@@Hal9023 Very true - Organized chaos for sure. I was with a photographer friend of mine during a nascar race at MIS, down on the pit wall during the race - about shit my pants to see that 5 feet away. On the same note, the precision of an F1 stop is also art in motion. So much pressure
@@radamus210 it’s true, if a guy messes up in a NASCAR stop, depending on where he messes up it may cost a bit of time but in f1 if one guy messes up it’s a 10 second stop.
Really miss seeing the well tuned NASCAR pit crews. Only a few people over the wall doing everything and watching them tighten 5 lug nuts per wheel in seconds. F1 would benefit from this kind of pitting.

this is pretty cool, I was involved in designing the wheel nuts (and hubs) for my school's FSAE car and it's neat to see how the pros do it. We also machine centerlock nuts out of aluminum, but pit stop times aren't particularly important for us so we use a simple clip for retention
I've actually got a Caterham one from 2014 when they were auctioning off old bits to get to the last race of the season. (cost me a lot less than £1000 though! ). Now I know why it has a green plastic ring on it :)
The spline drive wheel nut / socket was developed in 1994 by a small company named “Metalore” (who are still involved in F1, Prototype and Sports Car Racing) Newman / Haas was their test team in 1995 and Metalore was also the 1st distributor of Paoli Pit Guns in North America. By 1996 every team in the CART paddock ran that design and it became the norm world wide.
Kenny at Metalore had long been friends with John Barnard and we used them to make all our axles and CV joints etc (anything out of 330M) at Ferrari and later at TWR and Prost. Those splined features were on the JB Ferraris around that time and so I wouldn't be surprised if they were a result of collaboration between Kenny and JB.
@@GPRaceSimulation Yes - Kenny and JB were good friends. And still best mates up until Kenny's passing in 2022. It was actually Gordon Kimball who came up with the spline drive socket / nut solution for us to complement our drive line components we developed for Newman Haas (I work for Metalore as their track side support rep in North America). Kenny would also smile saying the only time F1 learned something from CART. We still use 300m + various other materials for today's modern driveline systems.
I never thought THAT much efford went into designing and making the weel nuts. It's easy enough to see why the engine or the bodywork is so expensive (only to constantly see cars that lost bits of the later doing the exact same times as before), but the attention to detail that goes into the small parts gets overlooked so easily.
It's a spinning object, so every gram it has gets magnified when the car gets up to speed. Excess weight in the wheels affects acceleration, braking, and cornering at all speeds whereas a lot of the bodywork only starts to work at higher speeds.
@@washellwash1802and also it's a part that comes off and goes on the car every Grand Prix. With the minuscule time spent on doing that it makes it pretty easy to see that effort is needed in designing it.
With the wheel guns being spec I honestly thought the wheel nuts were also a shared part just like the tyres, I had no idea so much innovation went in to wheel nuts, it’s nuts 🥜 😂

My 1960's Trumphs, MGs and Sunbeams with wire wheels also had a winged, center nut, and all came with a lead mallet with wooden handle to secure and remove them. Even though the lead was soft, it still dented the chrome plated nut wings a bit.
Pure aluminium is soft yes. But that's not what is used. Aluminium alloys can be both hard and strong. And as a machinist that have worked with materials from basic aluminium alloys (it's never used pure) to heat resistant superalloys like Inconel I know that machinable aluminium alloys are among the easiest to work with. However I'm sure the alloys in these are very specific, perhaps custom made. I wouldn't be surprised if several teams use secret alloys, thus the in-house manufacturing (otherwise they would save a lot by buying from one external shop, it ain't a difficult part with unusual requirements)
They are not permitted to use the more exotic alloys. All the teams are mandated to use the same alloy. The entire materials list for braking systems must be published openly. No exceptions. So, no, none of the teams are using secret intergalactic alien space metals.
@@martinbrandmuller8272 7075 T6 to be precise, it’s a tempered (and thus hardened) version. But as it isn’t really heat resistant due to dispersion of the carbide molecules, alloys of the 2XXX range are used for higher temp applications
Sorry this is probably a stupid question instead of aluminum alloy why don't teams use titanium nuts. Because if I'm not mistaken titanium is light but strong. So there is less chance of stripping the nut.

Hammer on and off wheel nuts were common place on British “sports cars” with wire spoked wheels up until the early 1970’s. Cars that had the optional wire spoked wheels with “spinner” wheel nuts (hammer on and off style as opposed to hex nuts) came with a short handled 2&1/2 pound “hard”:lead hammer in there tool kit along with the cars jack in the boot of the car. Also available with spoked wire wheels was a large hex nut which also came a hand use only socket and a bar to loosed/tightened the wheel nut. Both wheel nuts were stamped with a L if they were left handed thread. Additionally Wire spoked wheels and hammer on and off wheel nuts were an option on some Alpha Romeo’s as well.
That's right, this video is a little misleading in only talking about racing after WW2.. Centre lock wire wheels were common on British cars before the war and also were left and right threaded for the reasons stated in this video. For anyone who has had a classic English sportscar this stuff is nothing new.
I used these on my lowrider I kept a mallet in the trunk and once a week or whenever I was thinking it I would take out the mallet and give each wheel a good couple wacks. Totally makes people nervous when you're talking with them and you just pull out a 4 pound dead blow with a defeated dead pan look.
My uncle, an amateur stock car racer in the 1960s and '70s, had a lead hammer. He said it was used to tighten the spinners on the threaded center hub of racing cars. But, I saw him use it on steel doors and door frames (he built, installed, and repaired them) and to hammer out the dents on the fenders of his race car.
Super piece Scott! WOW! I had no idea of this throwaway expense - incredible. On Bottas nut in Monaco the gun man basically made the gun a stump grinder. Do some of the teams use a gun with a safety button on the inside for positive engagement to prevent this? Thought I'd picked that up somewhere.
That's my thinking too, it would make sense to have pressure operated switch inside the wrench socket and the wrench only activates when enough pressure is detected (say, 20N). This would require the wrench operator to just hold the trigger while pressing the gun towards the nut and when pressed hard enough, it takes off the nut. And if the slots do not engage, you couldn't apply the 20N pressure no matter how much you press.
I imagine downside would be more parts means more failures. And maybe adds a tiny amount of time too to register and activate. For how rare that happens not worth it. @@MikkoRantalainen
@@simonwadd4038 Yeah, and I've later found out that the wheel guns are standardized / regulated, too, so if the gun doesn't have such feature it cannot be added by the team either.
I learn something new about F1 cars everyday. Your videos are so insightful while also being easy to digest and you get straight to the point instead of relying on off color jokes or random skits.
As a mechanic who services and works on cars every day this has been one of the most interesting parts of motorsports to me, particularly how why try to avoid cross threading of the nuts on the spline whilst not having to hand thread them first
The machining is better, but worst case, the nuts are softer than the stub, so it would only happen that one time then be taken off and changed out for a new nut.
Dad was an old school panel beater, and used to do lead-loading, instead of plastic putty on a gentlemans Maserati, and it had knock-on hubs with the very damaged hammer in the boot. Hi from Melbourne, Australia.
The tri-winged center wheel nuts weren't just because there were no impact guns powerful enough at the time. It's because the racing regulations required only the driver (and navigator) to work on their own disabled car. No mechanic can help if they blew a tire on track. Thus a single mallet could be used by a driver to replace a wheel, and it was small enough to be stored onboard. A 2 meter long breaker bar and socket was much to big and heavy.
Not sure if I should say this or not. I want money if it becomes a thing. But what if you can develope a wheel nut that tightens automatically when you drive the car away? You only need the impact gun to take the old nut off. The new auto tightening wheel nut can be held in place with a pin that it ment to brake away once the nut is tight enough. Imagine the time it could save on the pits. You can use weak magnets to hold the tires in place until the car starts to roll away. Then the nut self tightens.
Actually the drawing does show red is left and right is green like a boat. He said it the wrong way round. I rewound and checked as it sounded wrong to me as a sailor!!
Yes, because if they were sailors they would be unable to distinguish from what situation they are in... A sailboat or an F1 pit - they are soooo similar😂 I know he said it wrong in the video, but why the heck should a sailing interested engineer have trouble distinguishing racing cars from sailing, they can't be that daft?😂 Pre så crew are helped by the fact the heating covers are marked with text so if they just can depart front from back and left from right the wheels will be delivered to the correct corner of the car😊
WOW! i had no idea the reason old wheel lugs had those wings on them! I thought it was for looks or aerodynamics! They actually hammered the nut on with them :D
1:40 Radical uses left handed thread on the left side of the car. V8 Supercars uses left handed thread on the right side of the car and different GT3 car’s alternate between sides depending on manufacturer. Is there a reason for this beyond different philosophies?
That was some "slick" editing on the word "Shrouds" lol. So if the wheels aren't able to be reused can they melt them down and re-cast or send them back to have them re-cast and recycle the wheel nuts bringing down costs?
I don't think there would be much saving in the raw materials its probably the machining and manufacturing of the part that puts the cost up so would be the same no matter if they used recycled metal or not.
The nuts aren't cast, but machined from a billet of aluminium, hence the massive costs. Casting isn't accurate enough to be used in that setting. Also the possibility of impurities or internal weaknesses makes it unsuitable for high performance parts.
he regenerative system can completely replace the wheen nut, a quarter inch thick of metal has zero resistance to direct current. So the right hand rule expands outward, but through shells, eacj shell is crazy glued to the next shell, so th resistance remains close to zero and moves back and forth by reverse interference winding layers, then you can pay somebody a years salary for free 500HP wheel nuts. I thought about it making a go kart, its just the arcing, or power transmission that took a little tweaking, first idea was to use ball bearings to deliver the power betwean the shells, (inner and outer).
I thought the left hand threads would be on the left (nearside) of the car so they would naturally tighten under braking? Or am I missing something here?
honestly, if you can win your first race in a competitive series, thats pretty good. i dont know how cimpetitive that series is or how many cars there were. but on ovak track in the states, winning a race with 20 cars really is an accomplishment. and ive never seen a driver even be in the top 10 in their first ever real race
Great info and breakdown into f1 wheel nuts. I started this video just find out why they are so expensive but in the end I was disappointed by your answer because 1 wheel nut doesn't cost over 50k. It's all the wheel nuts they use over a weekend of racing cost over 50k. 😑
I fall into the category of those who love it dearly. Back in 1999, I was working in a group home and we took the kids (teenagers) to see 'The Iron Giant.' One of them got mad when they realized we were watching a cartoon. Afterwards, they said it was their favorite movie ever.
I am pretty impressed with the information about the F1 parts and how things are done during a race. The only part of this video that bothered me the slightest, was the USB image at 5:53 showing 3 copies of the same USB, 1 and 3 in the "Label Upward" position and number 2 in the "Label Downward" position. Yet the 2 identical images were named both "wrong" and "correct". I do not see the point of that image. USB type A can only be inserted in 2 different directions (unless you are not trying to align it with the connector). 1: The attachable direction, where the connectors go together. 2: The upside-down direction, where the connectors don't fit. Sorry for the tangent, I am nitpicky by nature. Maybe the image should have been cropped more.
Its a joke. Everyone has experienced trying to insert a usb and had to flip it *at least twice* to get it in. Especially when you cant see the socket because its on the back of the box.
Going back a few years, I made the gun sockets for Lotus F1 for the start of the season in Melbourne, I still have one now. Like this comment if you want me to post a video of it.
6:55 have you any idea how much that hurts? I know they use colours to denote thread direction and not which side they are used, but on planes and boats red, left, port are all on the same side. That's where the red/green colour scheme come from. All the short words one side: red, left, port. All the long words are on the other side: green, right, starboard.
As a sailor, I immediatly picked that up and went to check the diagram. Another mnemonic to remember port/starboard/red/green/left/right. - "There's no red port left in the bottle".
@@steven1000000000 Also, in UK (I don't know about other countries) it's common to have the hot water tap on the left.. But then, we haven't wholly caught on to the idea of mixer taps, but we're getting there.
@@dougaltolan3017 In the US the hot water is normally on the left. Except in my house.. When I bought it all the taps were wrong way around, and all the light switches were installed upside down. No idea why, maybe a previous owner had a superstition?
They are made in house with a machine they already own by an employees already employed. Cost is very minimal. Especially when the make so many. Volume drives the costs down significantly. Recouping R&D and materials is where the price comes from. I have noticed a lot of F1 price estimates reuse a factor multiple times as well to inflate the numbers. Crude example, X part takes a CNC mill to make. The mill cost x amount, machine price / total x parts made = cost per part. But they don't tell you that machine also makes 10 other parts therefore reducing the total cost per part bast on the machine. I think Mercedes had a virtual F1 factory tour online that kind of indirectly pointed this out.
I was going to make this comment. Once the CAD and toolpaths are done, aside from the material those costs seem ridiculous. The metallurgy in a piston is a whole different ballgame of course.
Very early races they had a ride along mechanic. Had to change spark plugs during race (in pit), manually pump oil during race, spotted following cars for driver (no rear-view mirrors!) en.wikipedia.org/wiki/Riding_mechanic
Who knew that the secret to making a million dollars in F1 was as simple as tightening a few nuts? I guess that's what they mean by 'turning a small fortune into a big one'!
I keep hoping F1 will bring back re-fueling. It was such an important part of tactics. How much fuel and when, affecting pit stop length and tire wear. Why not use titanium or something harder than aluminum for wheel nuts?
@6:55, I thought something was up with the colour coding. red is used for left and green for right on aviation and naval vehicles. The diagram also shows this same colour coding. I guess it was a slip of the tongue by the narrator.
9:47 Id love an F1 with NO BANS ON TECH BUT after 1 or half a season they have to open their book. No more "oh moveable aero, BANNED HAHA! " stifleing cool innovation, but no runaway either where big money = instant win
I've been fascinated with these specialized wheel nuts for a while now, always wondered how they were designed and how they stay locked to the wheel when removed from the car. I'm glad finally have a video talking about them, as they're never mentioned when talking about bigger things about the cars like engines and aero.
Dude, you should google the size of the torque wrench you would use if you owned a brand new porsche gt3 and manually were to tighten your centrenut on each rim 😂.
I remember the old Australian touring car races. The wheel nuts were the same ones that went on a standard car and a pit stop could take two and a half minutes.
@@andrewahern3730 But in NASCAR, those pit stops were FAST. Sure, they weren't required to get all five nuts properly on after a stop, but still. Impressive to see how fast they got those 5 wheel nuts off each wheel and get the new ones on
There is another factor in the high manufacturing cost. Machine shops grossly overcharge. I know because I've dealt with one in Sussex some years ago who did work for BAR at that time. The sort of figures he quoted me put me off having parts made for an RC model car. I mean the figures were downright hideously expensive. Then he said he'd need a so called 'consultation' fee, if I were to engage him making those parts, when I'd already produced detailed engineering CAD drawings for each part. That's when I really realised I needed to change career and I did.!
If you are shearing off the castellations on the wheel nut then sounds like you need an (very simple) interlock that does not allow the torque wrench to fire until fully engaged.
“after all the effort, it was banned next season” sums up f1 so well
“Peak innovation” yeah, that’s why endurance racing teams are literally “prototyping” engine tech. F1 is a little confusing when you start thinking about what the intent of certain rules are

Scrolling with no other purpose than to find this comment. 😂
I was confused, skimming around looking for an 8 sided hex nut equivalent, then I finally heard it. Missed that the first time i watched the video.

I like how Scott compared the USB cable connection with the wheel nut. I hate the USB and never get it right at the first try.
USB C cannot be inserted incorrectly, it connects in either possible direction.
I used these on my lowrider I kept a mallet in the trunk and once a week or whenever I was thinking it I would take out the mallet and give each wheel a good couple wacks. Totally makes people nervous when you're talking with them and you just pull out a 4 pound dead blow with a defeated dead pan look.
Should probably mention that the hammer on/off nuts are called knock offs 🍻
My uncle, an amateur stock car racer in the 1960s and '70s, had a lead hammer. He said it was used to tighten the spinners on the threaded center hub of racing cars.
But, I saw him use it on steel doors and door frames (he built, installed, and repaired them) and to hammer out the dents on the fenders of his race car.
Super piece Scott! WOW! I had no idea of this throwaway expense - incredible.
On Bottas nut in Monaco the gun man basically made the gun a stump grinder. Do some of the teams use a gun with a safety button on the inside for positive engagement to prevent this? Thought I'd picked that up somewhere.
That's my thinking too, it would make sense to have pressure operated switch inside the wrench socket and the wrench only activates when enough pressure is detected (say, 20N). This would require the wrench operator to just hold the trigger while pressing the gun towards the nut and when pressed hard enough, it takes off the nut. And if the slots do not engage, you couldn't apply the 20N pressure no matter how much you press.
I imagine downside would be more parts means more failures. And maybe adds a tiny amount of time too to register and activate. For how rare that happens not worth it.

@@simonwadd4038 Yeah, and I've later found out that the wheel guns are standardized / regulated, too, so if the gun doesn't have such feature it cannot be added by the team either.
@10:50 now that's nuts
Didn't know these nuts exists
I learn something new about F1 cars everyday. Your videos are so insightful while also being easy to digest and you get straight to the point instead of relying on off color jokes or random skits.
If they fail that's when they cost way more...
Replacing an F1 car after it gets totaled in a racing accident is around 16 million dollars.
This was very interesting! Good video!
50 000 per race? THAT IS NUTS!
No! 50'000 per race! I don't have any idea what that means!
Lots of nuts
So one nut does not cost 50000 as the title states. Clickbait.
Impressive and informative content, keep it up, Driver61, I love your videos. ❤
I never thought I'd be interested in wheel nuts but as usual this channel always surprises me with this type of educational content.
They're now my obsession. O_O
@@SelectCircle That's nuts......
Those prices are nuts!
I was so pumped after Monaco quali, that I installed my new long cranks. And I used an orange 2lbs urethane mallet
Sauber seems to have a cheaper version💀
Came here for this.
6:55 No, the right side are green and the left side are red (as it should be) and as the drawing details calls for.
As a mechanic who services and works on cars every day this has been one of the most interesting parts of motorsports to me, particularly how why try to avoid cross threading of the nuts on the spline whilst not having to hand thread them first
The machining is better, but worst case, the nuts are softer than the stub, so it would only happen that one time then be taken off and changed out for a new nut.
Yeah every time I see them blast the nuts on all I can think of is a cross threading!
Dad was an old school panel beater, and used to do lead-loading, instead of plastic putty on a gentlemans Maserati, and it had knock-on hubs with the very damaged hammer in the boot. Hi from Melbourne, Australia.
The tri-winged center wheel nuts weren't just because there were no impact guns powerful enough at the time. It's because the racing regulations required only the driver (and navigator) to work on their own disabled car. No mechanic can help if they blew a tire on track. Thus a single mallet could be used by a driver to replace a wheel, and it was small enough to be stored onboard. A 2 meter long breaker bar and socket was much to big and heavy.
Not sure if I should say this or not. I want money if it becomes a thing. But what if you can develope a wheel nut that tightens automatically when you drive the car away? You only need the impact gun to take the old nut off. The new auto tightening wheel nut can be held in place with a pin that it ment to brake away once the nut is tight enough. Imagine the time it could save on the pits. You can use weak magnets to hold the tires in place until the car starts to roll away. Then the nut self tightens.
You're the smartest TH-camr I've ever encountered. O_O
And the extra weight of this design is...?😊
The right side nuts are red and the left are green? Apparently none of the engineers are sailors.
Actually the drawing does show red is left and right is green like a boat. He said it the wrong way round. I rewound and checked as it sounded wrong to me as a sailor!!
Yes, because if they were sailors they would be unable to distinguish from what situation they are in...
A sailboat or an F1 pit - they are soooo similar😂
I know he said it wrong in the video, but why the heck should a sailing interested engineer have trouble distinguishing racing cars from sailing, they can't be that daft?😂
Pre så crew are helped by the fact the heating covers are marked with text so if they just can depart front from back and left from right the wheels will be delivered to the correct corner of the car😊
Your site is the best for INFO on Formula 1 ...thank you for all the effort :)
WOW! i had no idea the reason old wheel lugs had those wings on them! I thought it was for looks or aerodynamics! They actually hammered the nut on with them :D
My 61 Austin Healey 3000 came with a brass hammer to get the wheels off and on.
They are called Knock-off nuts...
If there is a retention system, what's the point of screwing it on? Just only use the retention system and that should save a lot of time, right?
Hex has 8 ways? Are you counting 2 of the 6 flats twice?
It's a mythical 8-sided hex nut. As rare as unicorn....
1:40 Radical uses left handed thread on the left side of the car. V8 Supercars uses left handed thread on the right side of the car and different GT3 car’s alternate between sides depending on manufacturer. Is there a reason for this beyond different philosophies?
What a Quali😳
0:09 didn't know there was 4 numbers after the 16 for sixteen thousand
That was some "slick" editing on the word "Shrouds" lol. So if the wheels aren't able to be reused can they melt them down and re-cast or send them back to have them re-cast and recycle the wheel nuts bringing down costs?
I don't think there would be much saving in the raw materials its probably the machining and manufacturing of the part that puts the cost up so would be the same no matter if they used recycled metal or not.
The nuts aren't cast, but machined from a billet of aluminium, hence the massive costs. Casting isn't accurate enough to be used in that setting. Also the possibility of impurities or internal weaknesses makes it unsuitable for high performance parts.
@David Wilhelmsen They are very much machined from cast aluminium. At least, in mercedes' case they are
he regenerative system can completely replace the wheen nut, a quarter inch thick of metal has zero resistance to direct current. So the right hand rule expands outward, but through shells, eacj shell is crazy glued to the next shell, so th resistance remains close to zero and moves back and forth by reverse interference winding layers, then you can pay somebody a years salary for free 500HP wheel nuts. I thought about it making a go kart, its just the arcing, or power transmission that took a little tweaking, first idea was to use ball bearings to deliver the power betwean the shells, (inner and outer).
Who else is here after watching Monaco Qualifying?
Is alonso still pole
@@alkaragini5003 verstappen pole alonso p2
I am happy and also sad.
so close for alonso
Wtf is a monaco? Stop making shit up
I thought the left hand threads would be on the left (nearside) of the car so they would naturally tighten under braking? Or am I missing something here?
honestly, if you can win your first race in a competitive series, thats pretty good. i dont know how cimpetitive that series is or how many cars there were. but on ovak track in the states, winning a race with 20 cars really is an accomplishment. and ive never seen a driver even be in the top 10 in their first ever real race
New title, why several wheel nuts cost 50,000. Interesting video despite the misleading title.
Great info and breakdown into f1 wheel nuts. I started this video just find out why they are so expensive but in the end I was disappointed by your answer because 1 wheel nut doesn't cost over 50k. It's all the wheel nuts they use over a weekend of racing cost over 50k. 😑
I fall into the category of those who love it dearly. Back in 1999, I was working in a group home and we took the kids (teenagers) to see 'The Iron Giant.' One of them got mad when they realized we were watching a cartoon. Afterwards, they said it was their favorite movie ever.
6:50 the part drawing is fun to see. Rather basic GD@T but it is from back in 2014
6:53 port-side red is left starboard green is right, Looks
like they got it right on the plan except for the spelling.
6:56 misread this part. Left side red, right side green. Same as navigation lights on planes/boats.
This pricing is nuts.
I am pretty impressed with the information about the F1 parts and how things are done during a race. The only part of this video that bothered me the slightest, was the USB image at 5:53 showing 3 copies of the same USB, 1 and 3 in the "Label Upward" position and number 2 in the "Label Downward" position. Yet the 2 identical images were named both "wrong" and "correct". I do not see the point of that image. USB type A can only be inserted in 2 different directions (unless you are not trying to align it with the connector). 1: The attachable direction, where the connectors go together. 2: The upside-down direction, where the connectors don't fit. Sorry for the tangent, I am nitpicky by nature. Maybe the image should have been cropped more.
Its a joke. Everyone has experienced trying to insert a usb and had to flip it *at least twice* to get it in. Especially when you cant see the socket because its on the back of the box.
Going back a few years, I made the gun sockets for Lotus F1 for the start of the season in Melbourne, I still have one now. Like this comment if you want me to post a video of it.
They correctly colored the wheel nuts. Right is green, Left is red. The narrator reversed it.
6:55 have you any idea how much that hurts?
I know they use colours to denote thread direction and not which side they are used, but on planes and boats red, left, port are all on the same side. That's where the red/green colour scheme come from.
All the short words one side: red, left, port.
All the long words are on the other side: green, right, starboard.
As a sailor, I immediatly picked that up and went to check the diagram. Another mnemonic to remember port/starboard/red/green/left/right. - "There's no red port left in the bottle".
@@steven1000000000 Also, in UK (I don't know about other countries) it's common to have the hot water tap on the left..
But then, we haven't wholly caught on to the idea of mixer taps, but we're getting there.
@@dougaltolan3017 Never thought about that one, but yeh that works.
@@dougaltolan3017 In the US the hot water is normally on the left. Except in my house.. When I bought it all the taps were wrong way around, and all the light switches were installed upside down. No idea why, maybe a previous owner had a superstition?
>Why they cost 50k pounds
>Oh except they actually cost about 1k pounds
Clickbait. Downvoted, reported.
Why? Because they are willing to pay that much for them; bread would cost $100 too if there were customers for that.
thx for the footage sources
They are made in house with a machine they already own by an employees already employed. Cost is very minimal. Especially when the make so many. Volume drives the costs down significantly. Recouping R&D and materials is where the price comes from. I have noticed a lot of F1 price estimates reuse a factor multiple times as well to inflate the numbers. Crude example, X part takes a CNC mill to make. The mill cost x amount, machine price / total x parts made = cost per part. But they don't tell you that machine also makes 10 other parts therefore reducing the total cost per part bast on the machine. I think Mercedes had a virtual F1 factory tour online that kind of indirectly pointed this out.
I was going to make this comment. Once the CAD and toolpaths are done, aside from the material those costs seem ridiculous. The metallurgy in a piston is a whole different ballgame of course.
In the next decade, F1 teams will have more lawyers trying to find loopholes in F1 rules than engineers coming up with better designs.
I'm adding this to my "videos with thumbnails that immediately ignite my psychotic rage" playlist
6:00 “these HEX nuts have eight ways they can locate correctly”. Urmmm, you sure about that? 😂🤦♂️
Wow! Love the way that F1 innovates. Just wish we got to see more of these details analysed on TV.
Watching the history of Le Mans recently and seeing them change the tires by hammering them out was wild haha
Very early races they had a ride along mechanic. Had to change spark plugs during race (in pit), manually pump oil during race, spotted following cars for driver (no rear-view mirrors!)
en.wikipedia.org/wiki/Riding_mechanic
wow thats pretty nuts.
6:54 "RIGTH HAND", nice to see I'm not the only one who makes spelling mistakes on drawings, hehe.
Who knew that the secret to making a million dollars in F1 was as simple as tightening a few nuts? I guess that's what they mean by 'turning a small fortune into a big one'!
I love this vidéo, that show more and more the technologies about the f1, and show us how f1 is incredible.
thx for clarifying why the wings used to be on the 60s cars.
I keep hoping F1 will bring back re-fueling. It was such an important part of tactics. How much fuel and when, affecting pit stop length and tire wear.
Why not use titanium or something harder than aluminum for wheel nuts?
I was wondering why not titanium.
@6:55, I thought something was up with the colour coding. red is used for left and green for right on aviation and naval vehicles. The diagram also shows this same colour coding. I guess it was a slip of the tongue by the narrator.
9:47 Id love an F1 with NO BANS ON TECH
BUT after 1 or half a season they have to open their book.
No more "oh moveable aero, BANNED HAHA! " stifleing cool innovation, but no runaway either where big money = instant win
i appreciate the timer at the bottom of your ad breaks
6:58 curious they used the same colours and port and starboard but on the wrong sides!
Or did he misspeak?
F1 tech continues to be awesome. So much does trickle down to what we drive.
4:01. OK, here's the problem. Using S.A.E. wrenches on metric parts.
I've been fascinated with these specialized wheel nuts for a while now, always wondered how they were designed and how they stay locked to the wheel when removed from the car. I'm glad finally have a video talking about them, as they're never mentioned when talking about bigger things about the cars like engines and aero.
Dude, you should google the size of the torque wrench you would use if you owned a brand new porsche gt3 and manually were to tighten your centrenut on each rim 😂.
I remember the old Australian touring car races. The wheel nuts were the same ones that went on a standard car and a pit stop could take two and a half minutes.
NASCAR was that way until recently (still is in lower divisions). Helmets are definitely necessary with cars peeling out spraying lug nuts
@@andrewahern3730 But in NASCAR, those pit stops were FAST. Sure, they weren't required to get all five nuts properly on after a stop, but still. Impressive to see how fast they got those 5 wheel nuts off each wheel and get the new ones on
Now this is excellent content my friend
Excellent coverage, very detailed and comprehensive, thank you very much.
Man this episode is nuts
There is another factor in the high manufacturing cost. Machine shops grossly overcharge. I know because I've dealt with one in Sussex some years ago who did work for BAR at that time. The sort of figures he quoted me put me off having parts made for an RC model car. I mean the figures were downright hideously expensive.
Then he said he'd need a so called 'consultation' fee, if I were to engage him making those parts, when I'd already produced detailed engineering CAD drawings for each part. That's when I really realised I needed to change career and I did.!
One would think that an F1 team would have their own machines and don't have to contract a 3rd party vendor.
@@MrSkywalker121 There's never enough time, and never enough machines in the shop.
Lotus Elans also used the 3 winged nuts and a mallet was part of the tool kit.
Got 2 race used ones from Mercedes at Bahrain 2013, very light for the size
My whole net worth is less than a god damn wheel nut.
If you are shearing off the castellations on the wheel nut then sounds like you need an (very simple) interlock that does not allow the torque wrench to fire until fully engaged.
i loved learning about these nuts
Great information and video, it made me subscribe.
8:26 Four-second pit stop. If you missed it, go back, it's worth it!
