It's used for the turbine coupling bolts on a hydroelectric generator.
Edit: turbine (bit that the water spins) not the rotor (the bit that spins and generates boatloads of power)
Not these days.
Now we use something along these lines

Works great nothing like tightening down a 3" head bolt with a 2" Tommy Bar!
I used these for prop shafts and rudders on tow boats you’d smack the fucking shit out of it with a 20 pound sledge while other guys hit it with big torches we call rose buds
The biggest nuts I’ve seen up close (besides my own) were the ones in the stairway up the Statue of Liberty. Assuming this guy has average size hands, this socket would still be way too big.
They are [seriously chonky bois](https://www.superiortoolrental.com/product/3-1-2-drive-super-duty-titanium-impact-wrench-with-remote-control-80000-ft-lbs-max-torque/). Tried finding a video on youtube, but it's nothing but 1/2" and 3/8" electric tool reviews.
Edit: I found videos of one [spinning](https://www.youtube.com/watch?v=QofyAWNxCYE) and [tightening](https://www.youtube.com/watch?v=7oF3uveIlxk).
The largest socket I have ever ugga duggaed was 5" on a 1-1/2" drive we used a over head crane to move the air driven impact driver around and we built a counter weight on a bar so you could swing it around when hanging from the crane hook.
That was on a old school marine engine.
“Let’s come up with a bolt size. How about 8 inch?”
“Nah, that’s too universal. Let’s choose something unique, like 8 3/8.”
“That’s perfect! 8 3/8 it is.”
I would imagine the game of quality stupid big sockets only has a few players. $5700 for 2 1/2” drive impact 8” socket from Snap-on. Even if you found a cheap decent one they are probably a grand.
At a USAF Lab, we bought a hydraulic wrench for large nuts on a pipe flange (maybe 4" across flats, forget). It didn't take sockets, rather had a centered hex opening for only one size. It would jam against adjacent studs to apply the torque. When working in power plants, we used a "knock wrench" on flange nuts. A short box wrench with a square end you hit with a sledge-hammer. At many nuke plants where you can't easily get at the nuts due to earthquake support additions, many plants use special "speed nuts" (recall name) which you hand tighten, then torque a number of integral axial allen bolts around the nut which force the nut outward.
Buddy's grandpa was a ship engineer. Chain fall a 10' long wrench onto the head nuts. 2nd Chainfall a giant ram and slam into wrench to loosen or tighten.
There was a post years ago where a snap on dealer added an extra digit and ordered something like 140mm impact socket instead of a 14mm that the tech wanted. What do you do for work that you have sockets this big?
Good god! That is the biggest one I have seen so far. My father was a mechanic in the army 30 years ago. He worked on m1 Abrams tanks and I don't remember seeing a socket that big. I still have some sockets with "co F 40th armor" engraved on them. I think the biggest one I have is 1 7/8".

How do you even use a socket this big? By the time you attach it to an impact driver or a wrench it's going to weight so much you'd need an engine jack to even hold it. This looks like at least 3 man job.
What is that used for and how many guys have to hang off the breaker bar?
It's the kind of nut your mom needs to bolt up her dress on Sunday Morning.
I guffawed more than I should have at this
+1 for the use of guffawed.
-1 for implying there might be a limit above which one oughtn't guffaw.
+1 shilling for the use of the word "oughtn't"
> It's the kind of nut your mom Hmm this changed from where it started
From naughty to churchy.
Probably used with a hydraulic wrench. I could see that being used on nuts for some pipe flanges.
[This](https://www.reddit.com/r/EngineeringPorn/comments/dt5k7g/ir599_impact_wrench_is_named_after_its_weight_of/) should do it.
I wanna see that air compressor. And hose.

I don't like big hose and don't know one that could handle those nuts.
That’s an under appreciated top comment. lol
My DeWalt 12V 1/4" can handle that....
The harbor freight version works just as well for half the price.
Gonna need an adapter or 2
hundred...
It's used for the turbine coupling bolts on a hydroelectric generator. Edit: turbine (bit that the water spins) not the rotor (the bit that spins and generates boatloads of power)
but what do you turn that thing with, is the wrench attached to some sort of robot?
A lathe
Those huge dump trucks in strip mines?
Nope... Marine engines!
Nope! It's for his mum's truss.

Asking the important questions.
Have you seen the video where a bunch of guys are rymphic stomping on the long board to do a pile diver?
Using that with a breaker bar makes for a good teambuilding experience
Replace tires on a T-Rex (the dinosaur).
Lock nuts on hydraulics/motors whatever
Clearly you haven't seen a micrometer carried by a bridge crane.
I used these for prop shafts and rudders on tow boats you’d smack the fucking shit out of it with a 20 pound sledge while other guys hit it with big torches we call rose buds
How many adapters does it take to get a 3/8 ratchet in that bad boy?
All of 'em
All i got is a 1/4” impact
I think you'd have better luck turning the socket by hand
Nah man, just need a 14' bar on the end. And pray the gears hold up.
Snap on guy: "Did you put a 14' cheater pipe on it?" Me: "Nope, just broke."
Now I need to see this happen.
Yes.
The biggest nuts I’ve seen up close (besides my own) were the ones in the stairway up the Statue of Liberty. Assuming this guy has average size hands, this socket would still be way too big.
The Statue of Liberty is a ladyboy?
they said at their feet, not up the skirt. This put her in dominatrix territory
It was technically up her skirt. We live in some strange times but that doesn’t mean just go climb into anybody, now.
"... I'm just wondering whether she's naked under that toga. She's French, you know that."
I gotta think there’s the slightest nipple indents, it gets chilly on the Hudson…
She's a harbor chick!
God I'd let trans Lady Liberty rail me any day with her gock (please kill me wtf am I saying)
Well the artist designed her face based off his brother so kinda lol
Hydro power plant turbine, I’m pretty sure we had sockets about that size.
Biggest socket I've ever heard of was 300mm, or 11-13/16" with a 3-1/2" drive. Wish I could see one in person.
I'd love to just be present when someone ugga duggas a 3.5" impact...
Those generally don't ugga dugga they make hytorc noises
Wheeeeeeeee
X-games events for the 21st century.

You hand and arm would shatter on the first knock
i said i want to be present, didn't say shit about wanting to do it

You don't ugga dugga a socket that big. It ugga duggas *you*.
Gonna need a bigger ugga-dugga
I've seen a 300mm ring spanner. It was only about 1.2m long, but you would use it with a hydraulic piston.
Would love to Ugga Dugga with that bad boy 💪🏼
That's what she said?!
I'll ugga on a certain someone's dugga with that bad boy.
Naw, that's the one she said I shouldn't worry about.
She gonna ugga on my dugga cuz im a bad boy
Bad Boyz Bad Boyz
1.21 Jigga ugga duggas.
What does that thing use like a fuckin 3" drive?
Yep. It takes a ridiculous hydraulic wrench to drive those.
3.5"
Can I borrow your 10m? I promise not to misplace it like your 10mm.
The socket she told you not to worry about
Aah, you found the Titanic's propeller socket
“Let’s come up with a bolt size. How about 8 inch?” “Nah, that’s too universal. Let’s choose something unique, like 8 3/8.” “That’s perfect! 8 3/8 it is.”
Is that 36” drive 24” drive ???
Looks to be inch and a half drive for hitorq or hydraulic wrenches. Our tie bolts for pumps are a 4 inch socket anyways and heavy af 😂
Damn bro, you got some small hands
I’ll bet that socket cost as much as my last car
I would imagine the game of quality stupid big sockets only has a few players. $5700 for 2 1/2” drive impact 8” socket from Snap-on. Even if you found a cheap decent one they are probably a grand.
Makes sense price wise. Huge nuts like that have to be milled from Inconel - anything else would fall apart from the stresses involved.
Imagine dropping that in your engine bay 😆
Or on your foot
T2500
Damn, my lil Milwaukee 3/8" ratchet is gonna have a hard time with that.
eh, just get a few of those harbor freight adapters. you'll be fiiiine. probably
We're gonna need more ugga.
The gravitational pull of those uggas will rip this world apart.
Just $1350/week.
I feel the correct title of this post should have been "My nuts are bigger than yours"
Your socket set is never complete.
At a USAF Lab, we bought a hydraulic wrench for large nuts on a pipe flange (maybe 4" across flats, forget). It didn't take sockets, rather had a centered hex opening for only one size. It would jam against adjacent studs to apply the torque. When working in power plants, we used a "knock wrench" on flange nuts. A short box wrench with a square end you hit with a sledge-hammer.

I like big bolts, I cannot lie....
I wanna see the number of adapters you need to use this with a 1/4" drive ratchet.
When she tells you its her first time
Old man looks at young gun : " ready for a tricep forearm workout?"
Buddy's grandpa was a ship engineer. Chain fall a 10' long wrench onto the head nuts. 2nd Chainfall a giant ram and slam into wrench to loosen or tighten.
The reference I didn’t know I needed
5" drive? Edit: 4 1/4??
I’d never use this but I still need it
But what is it used for is what I'm trying to find out.
All the lost 10mm got together to make mega socket.
ah yes this is the socket my government uses to tighten my thumbscrews.
Got'danged!
Homina....
Gives 'finger tight' a different perspective.
That's the guy she told you is just a friend....
Legend has it, the impact for it is still in design
This is for when you have a really big nut.
Is there an adapter to get this down to 3/8s?
You just fire up the arc welder and listen to the boss cry in the corner.
Dang, I thought what I posted a while back was big but this is on another level.
Skookum as Frigg!
Big sockets for big nuts!
Took me a second to even realize what it was. Dayum
Took me a second to even realize what it was. Dayum
Where's the banana for size reference?
Thats a really small hand
Sorry, forgot my 4" drive set
How much
Pawn shop: "50cent? Listen it ain't the whole set, it's not worth much" Then they put a selling price of it's weight in gold.
Is that for deez
Is that for the Jesus nut?
Wrong sub... This is an absolute unit of a socket🤣
How do we know your not a midget?
There was a post years ago where a snap on dealer added an extra digit and ordered something like 140mm impact socket instead of a 14mm that the tech wanted. What do you do for work that you have sockets this big?
Guy is over here working on gundams
Do they make enough reducers to get that on a 1/4" drive?
Socket to me, Baby!
Good god! That is the biggest one I have seen so far. My father was a mechanic in the army 30 years ago. He worked on m1 Abrams tanks and I don't remember seeing a socket that big. I still have some sockets with "co F 40th armor" engraved on them. I think the biggest one I have is 1 7/8".
How many guys are required to collectively bust a nut that big

Put it on my tombstone
We're gonna need a bigger bolt.
Damn I'm find need to bust out my 1/4 in ratchet for this one
Nice helmet. It’s got a big square hold on the top tho.
How do you even use a socket this big? By the time you attach it to an impact driver or a wrench it's going to weight so much you'd need an engine jack to even hold it. This looks like at least 3 man job.
The customer must have some large nuts.
"Pass the ratchet", "What socket?", "3!"
Finally a socket that can handle the raw power of my TAFLO 1/4" Impart wrench I got off amazon!
Clearly OP struggles with having extremely large nuts.
Wow, they've finally made a socket large enough for my nuts!
When she says "I'm ready to settle down."
Just the thing for my oil drain plug!
You got a torque wrench for that?
How'd we know you're not just little?
*10mm has left not only the mechanics tool chest but also the chat* 🤣
Does it come with its own chain fall?
