I sold and used tools for almost forty years and a lot of people don't understand the difference between impact and standard sockets. Impact sockets are not only thicker but softer material to take the pounding affect of the impact gun. Hard chrome sockets are designed for the torqueing while using a ratchet or breaker bar. Now not saying you can't use either in each others place(the hard socket will give quicker on a impact gun) but I've always heard people say they wanted the impact socket because it was the premium socket and the hard chrome was not. If you buy a premium socket no matter which one and use it as intended and take care of it it will last a long time.
Chrome sockets on an impact most often deform at the square section first, but also crack at the socket walls. I think I've split more chrome sockets with an 8 inch ratchet over the years than I've ever purchased, not to mention broken every breaker bar I've ever had. I switched to using exclusively impact sockets for anything 9/16 and up, and I can recall only once ever breaking one with a hand ratchet. I use a 40 year old proto ratchet as my breaker bar these days, no one makes a breaker bar that lasts more than a few uses.
It would be nice if you put a comprehensive table at the end of the video. Prices, weights, dimensions, breaking forces and, most importantly, the price/force ratios.
@@gafrancisco He only showed the data on the material thickness for two of the socket wrench hads. I guess that it is this parameter to correlate the forces with. Not the price nor the weight.
1:34 The Bosch and Milwaukee sockets are both made in Taiwan. If you want to demonstrate a German made or USA made socket, then use brands that make sockets in those respective countries i.e. Gedore or SK Tools
I agree. US made brands would have been Proto, Mac Tools and Snap-On. Dont know any German brands but Czech tools would include Wera. This was basically cheap chinese socket vs multiple cheap Taiwanese sockets.
@@johnnycabra I would say cheap Chinese and slightly more expensive Taiwanese tools. And Taiwan produces some pretty good quality under brands that maintain good quality control. I also get that most home hobbyists don’t want to or can’t pay the price for the good made is USA brands, so buying Taiwanese at least still supports workers in a democratic free country. However I do trade work for a living so my tools are primarily SK, Williams and Wright with a smattering of stuff from Japan and Germany
They always try push Milwaukee as American but unfortunately it hasn't been a American company for almost 20 years it's owned by China and their tools are made with slave labor
I would think the true test of a socket, is the amount of torque it will withstand fastening and removing a bolt or nut. The tolerance between the socket size and the bolt head or the nut is pretty important. I would not base a purchase decision on this demo with the little hydraulic press.
What people don't understand, it's not the socket, it's the nut. A nut gets rounded when too much torque is applied. The really nice sockets have a notch inside to grip the edges of a nut. An impact socket is actually softer metal that won't shatter under load.
@@vasantos-re4hb I had a 30 year old Craftsman 18mm socket 12 sided for 3/8" ratchet. I never used it until few days ago, to remove a sway bar bushing bracket from a Mercedes. It cracked before the bolt got loose. So, I got out Craftsman 18mm long socket 6 sided for 3/8" ratchet. It cracked also. I went to Lowes to see if they are going to replace the socket for free, and they did. The new Craftsman 18mm socket I got from Lowes as a replacement did not crack, and was able to remove the bolt.
This test is not relevant at all. A softer material with thicker wall would score better but what you want is a hard material with thin wall so you fit in more places and when it slips over a nut your tool is still good.
As a technical draftsman and technician in mechanical engineering, I am not so sure about the usefulness of this test. The force applied to the top of the nuts/tools only, is very different from the force during use. Simply increasing the outside diameter would greatly improve these results, but the inside contour would still likely be destroyed at the same torque. Could you do a torque test to see when the tool shears off so the results show the actual forces during use of the tool. There is also a big difference between between impact and standard tools! greetings from germany
Also elect/Mach engineer, what's not clear to me the force of forward/ reverse movement with coupling both ends of the test article and to what kgs will the bending points tested to accumulate the correct defective force of the subject in question, the formula pls to value your findings. Thanks
My understanding is that sockets are susceptible to stretching, with use, beyond the yield point of the material from which they are made. I think that the hydraulic press could be used to assess this, but only by measuring deformation of the sockets at various loads. The whole time that I was watching this presentation, I was wishing that a dial gauge had been set up to measure changes in the outside diameter of the socket. Destructive testing of this nature tells us very little, indeed.
As a Taiwanese, my last job was as an employee of a tool factory, and I am an OEM for the world's major brand products. I am proud of the fact that quality creates reputation and brings a safer use environment.

The wall thickness determines strength (along with the material). Thin walls are very desirable because there is often little space. To be a fair test you should do thickness/breaking force.
@TorpedoX - Very true!! Plus people use impacts incorrectly too often. They are nice to get things snug, but then trying to get the proper torque on something is the best way to fully tighten nuts & bolts. If there’s no torque listed, then have fun!! 😂😂. Used to be in a tire shop and they staff would screw up and get lazy or stupid or both. One or another would tighten the crap out of a wheel and we would get a towing bill because of when the client would get a flat or try to rotate the tires themselves and they couldn’t get the lug nuts off or kept on snapping them. I would teach the staff again how to do it right and see what happened later. I would spot check and then the good employees would ask if I didn’t trust them,,,, it’s hard! We did keep record of who worked on what and if there were 2 vehicles by the same person with a problem, one before the first training and a second problem after we taught them again, they were fired. They would have had ample warning and opportunity to do it right. We would lose one or two staff a year, just for that thinking they could estimate the torque they were applying!!! Haha. That’s life I guess. It happened pretty routinely for over 40 years!! 😂😂
@TorpedoX The torque tables are for dry threads. The manufacturers of bolts do not allow grease or oil. Obviously the threads need the friction to work as planned.
Don't overlook the fact, the Bosch socket was a thin walled impact socket against the Milwaukee thick walled impact socket.. You're not comparing the same TYPE of impact sockets..
Germany tools are trash either way now and days you pay for made in Germany but they always do poor in tests like China made products or worse... I remember when Germany tools were top notch, trash now.
It was very thick and material looked soft. Absolute strength is not the most important property. These are used by hand and should be strong enough not to break. Soft material can round out in use and if the wall is too thick, you can't fit it in many places. For my eye, bosch was probably the best. Should be strong enough, was hard material and the wall was thin. The question is, is it worth of money for all.
@@teropiispala2576 This was only the Bosch green one for hobby use. Test the Bosch blue nut for professional use. Much better as Bosch are other german companies like Stahlwille, Hazet or Gedore. They make tools for professional use.
Tenho uns da force aq tem mais de 10 anos q uso na oficina e ta bem file ainda mas comprei uns de outra marca tem uns 5 anos e ja tive q substituir pq gastaram muito rapido
I must be some kinda strong then!! I have broken dozens of cheap sockets, big & small. When you have a 3 ft bar and are applying all the force you have on the end,,,, how much rotational force do you think you are applying? Mid level and up seems ok. The cheap stuff is generally crap. Especially when applying huge torque trying to break a nut loose.
The old one appeared to be the shortest. And when you pulled fixture up on the press, it appeared to have witness marks lower on the snout like it had hit the square hole section of the socket. That would have compounded the hoop stress force and likely why it seems to explode evenly as it was loaded at the top and the bottom.
Please test tools which made in Germany (Remscheid, Solingen and so on) ... ! ... And: nobody use tool's in this way and with this force! ... Sensless and rediculous. ... 👎
Every time a "tool in a hydraulic press" comes up, there's always some Milwaukee hate down here. Always. I know they're more expensive. But there's a mechanic here on youtube that says "cheap tools cost you money. Expensive ones pay you". I guess that's his way of saying "you get what you pay for."
Bosch surprised me with being the weakest of the impact sockets. Milwaukee isn't the strongest, but it's what I use and love their products. Thanks for the vid!
Bosch (electronic) tools are mainly used in the private sector, if you really value good tools you will get something else anyway. That's why I also think that Bosch is really one of the very last representative "German" tool manufacturers, especially since in the end only the brand is German.
In 40 years of turning wrenches I never saw a socket break in same manner as your test...they wore out on the inside walls. Toughest tools I ever used were Hazet.
So thick impact sockets are stronger than thin-walled chrome sockets?! I’m shocked! 🙄 Setting aside the fact that all the interesting tool brands are absent from this test for a moment…This isn’t really meaningful data. Increased durability through harder steel can make a socket more brittle, but still well within the range of the intended use. Also fit tolerance is important to pros. This test doesn’t have any real world benefit. As a retired tech I care about tolerances/ fit, wall thickness and durability (especially on impact sockets).
Everyone who actually uses stickers regularly know that sometimes only a thin walled socket fits in some spots. I've never in my life broken a socket but I have broken some bolts.
51 years ago in Czechoslovakia, I bought a key,,,Tona,,,similar to a gedora. I have used them professionally for 40 years and not one has broken. We mostly used the 30 and 32 wrenches (for the nuts on the half axles of the cars) No other brand of wrenches could withstand this. Well done Tona!
Would have liked to see Snap-On and/or Mac Tools in the mix along with Harbor Freight. Milwaukee isn't the first brand that comes to mind in the US when it comes to sockets.
@@QueenieTheDog They are equating a Harbor Freight Pittsburgh shop press with hydraulic jack cylinder with this medium sized dedicated hydraulic pump press. I have a Pittsburg '12 Ton' . Nice and square with bolts and welds.
This is the press channel. Also, a tapered mandrel, such as the one used, does create hoop stress in the socket. Torsion on the socket driving a fastener head creates hoop stress as well through a camming action. They are not exactly the same but I expect that a regression model could be developed to predict the strength of the sockets using either test. But it's still cool to break $h!+. (Destructive testing).
I break sockets with an impact wrench on a regular schedule because my boss buys cheap tools and those failures resemble these closley. The forces applied seem similar to me.
@@gabrieljordan9977 But it will fail under expanding every time because this is where the thinnest wall section is and the cutting of the hex or 12 point is the physical defect where the break will occur, so it is relevant.
Note very coarse grain structure on the Old socket. Coarse-grained steel is more brittle even at the same hardness. Modern metallurgy has improved grain size and toughness by huge amount.
@@limyrob1383 I had a 30 year old Craftsman 18mm socket 12 sided for 3/8" ratchet, which I bought when I was still in Highschool. I never used it until few days ago, to remove a sway bar bushing bracket from a Mercedes. It cracked before the bolt got loose. So, I got out Craftsman 18mm long socket 6 sided for 3/8" ratchet from the same set. It cracked also. I went to Lowes to see if they are going to replace the socket for free, and they did. The new Craftsman 18mm socket I got from Lowes as a replacement did not crack, and was able to remove the bolt. The 30 year old Craftsman were made in USA, and new one is from Taiwan.
I have been using force impact sockets for a 11+ years now and they get used everyday on milwaukee impact guns of all sizes every day and they are just as good as snapon and only a fraction of the price. Shout out to trade tools in noosaville!
For being able to work on my seat rails in my 1970 BMW (Changing the seat to a decent version, not that flat and able to be angled) I had to buy a very expensive ARAG socket head, compared to my old HERO, which was too solid made. The last functioned fine besides in this case.
It appears to me that different metals were used. Those that resisted higher force broke in a more brittle fashion, while those that broke at lower force broke in a more ductile fashion. With the exception of the "old" one.
I was expecting the old one to do better than it did given it looked like it had thicker wall than some of the others, but suffice to say that materials engineering is better today than in yesteryear.
na minha opinião a q rachou no meio com 4 toneladas é a melhor de todas material duro não tem desgaste em uma oficinha q usa diariamente as outas pode aguentar até 70 toneladas mas é macia sem durabilidade a que rachou com menos peso é a melhor de todas obebençendo o torque é uma ferramenta q passa de pai para filhos e netos e bisnetos as outras não
Unfortunately the forces shown breaking these sockets are unlikely to be replicated when they are used as intended. Sockets rotate. See if you can mange to test them that way. I lent a Britool socket to a friend when he was taking the head off a Rover 2600 (SD1) and he managed to break it. Replaced free of charge but I have never managed to break one myself.
Yes , sockets are meant to rotate , I wonders why testing them this way ? There is also difference in metalcomposition between impact sockets and regular ones , each should be tested in their own range .
my guess is it has, although not fully accurate, some correlation to the amount of outward pressure the socket can take before splitting, a particularly tight nut/bolt made of a really tough material could remain stationary while the socket turns as the socket stretches round the nut/bolt. i've split a few of sockets in my time, some through abuse (chromes on an impact wrench) others when used correctly, it's rare though as usually the nut/bolt just rounds off.
Most bolt heads on the engine and body parts in my 80series Land Cruiser have tapered heads so using 12 sided sockets is not a good idea. With these type of bolt heads the main contact area is right at the tip of the socket hence a lot stress in a small area of a socket
Cool video, very educational. Do you think the rankings would be the same if you did a torque test? You'd need new coupons for each test that are about ±5% dimensionally/Yield Strength, get at least 3 samples of each type of socket.
So, according to your test parameters and results - the best wrench sockets would be those made from rubber, which would continuously deform and not fracture!
El echo q se fabriquen en china no significa q sean de china se fabrican en china por qué la mano de obra aya es mucho más económica pero los materiales son de USA y otros países
The test doesn’t really mean a great deal, this situation would never be encountered anyway. It’s torsional strength they want to be testing. still, enjoyed it anyway.👍
those things cost way more than $5 per socket. the best one made , is the old socket . it did not give as like the others did. now that wa a very good socket. impressive video. thank you .
Your mistake was to expect that from this channel. There are other channels that do that kind of thing. This channel is just for watching things go crack-bang-smash.
La forma como el cono de la prensa ejerce la presión y extensión sobre el dado no es la misma que recibe durante el uso normal . No se qué tan significativos sean los valores obtenidos.
In the beginning of the video, I think either your camera lens needed cleaned or there is a plastic film over the lens. Still pretty cool how they hold up.
True. Also Bosch is not really known to be a high-quality producer of mechanical tools, and afaik none of them is manufatured in Germany, but in China. For tools actually coming from quality brands and manufactured in Germany that actual mechanics or professional garages etc. would use, please refer to "Stahlwille", Hazet or comparable brands for a better comparison. You can also include Wera if you want a high-quality Czech brand in the mix as well.
Taiwan has been making high quality items for decades. Yes, they still make budget items. Some Taiwanese will buy high quality items that will last DECADES, while others will buy lower quality and just replace things in few years. I prefer quality. My bookcases and furniture are 25+ years old and no warping. (Good solid teak and oak....entirely...no thin fake stuff on back side) I prefer my Cannondale with Campy parts bicycle....but Giant has been making top quality bicycles for decades....high enough for use in races like Tour de France.
the one with more sides, like the 12-sided one, will be stronger, as the pressure is more evenly distributed, on the other, it hits the tip, on larger surfaces on the 6-sided
SnapOn, Mack, S&K, Proto are American quality tool brand names. From chrome to hardened impact sockets. I tend to feel tools made 60 years ago are way better metal than in the last 30 etc. Not sure of exact timeliness. But you can feel the weight difference for sure.
Sadly I did try this out at home, I started out with a nice home, car, wife, and a hydraulic press the full deal, and then got hooked on these videos, now I live in ruins and assorted debris still with my Hydraulic press, I think I might need help with my addiction.
Could you please calculate the '' Pressure (kg)÷ Price($)＝value(kg/$)'' ,as a reference plz ?😁😁 I would be really appreciate.😃😃 Thus l could see whether it is worthy to spend my money💵💰, and check how exactly every dollar could bear how much press.
