20mm Sockets and Bigger

[cookiemonster]

Just wondering when you guys use 20mm sockets and up to the 30s for?

 

[R-C]

Axle nuts. Some suspension on bigger ton+ trucks. Heavy equipment. Ect

 

[Applesauce]

I kind of think I'm this board's lone bike mechanic, but I use 24, 26, 28, and even 36 mm sockets frequently on topcaps and overhauling dampers on mountain bike suspension forks.

 

[DTB]

Not very often for me.Mid 90s GM trucks have a large drain/fill plug on the transfer case around 30mm if I remember right.Axle nut socket for the GM trucks are 36mm.Standard lug nuts are 22(?)mm.That covers alot of what I use.

 

[ClrkLndeKmt'su]

I use 28mm on lots of lug nuts, 36 on a lot of spindle nuts, and a couple sizes in between. I belive I've ran across many many hydraulic fittings on German things that were 24mm

What's the torque like for those nuts.? Can they be removed with a 10 or 12" adjustable ?

 

[Mister Laugh]

Heavy Equipment, pretty much everything is big sizes in my trade.

 

[Fedwrench]

I have never used a 20mm socket, wrench yes, socket never.

21, 22, and 24mm are fairly common on suspension fasteners for me. 27 not as common but used once in awhile.

30, 32, 34, 35, 36mm deep impact sockets for axle nuts. get a 30 mm 12 point too for toyotas and the nut on chrysler output shafts.

Usually no more than a few tens of inch pounds tops. There is some resistance on removing the top caps sometimes due to dirt and o-ring resistance.

On the note of using an adjustable. It can be done (I have on many occasion) if the caps are not to snug and the crown does not restrict tool space. The big problem is that the components are generally built to be as light as possible and made from aluminum resulting in delicate parts. Many times the profiles on the caps are so low that the sockets may need to be ground down to remove the radius on the open end.

And I'm this board's lone loom mechanic. They're covered in 22s, and there are quite a few 24, 27, 30 and 36 mm bolts too.

At home I've used a 35 on axle nuts. Can't think of any others that I've actually messed with -- other than the t-case drain plug that DTB mentioned (30 mm), though I used a wrench for it.

 

[CJinPA]

I use a lot of those sizes working on atv/motorcycle/dirtbike. Mostly axle nuts and swingarms.

 

[jcbrew]

I use a 22, 24, and 27 on motorcycle axle nuts, and a 30 on top tree nuts

x2. 46mm on the big guy here.

 

[96snma]

36mm for the oil filter cap on my gf x3. Why they made it that big I have no idea because it gets torqued to like 25nm

 

[Cryptic1911]

22mm for a few large bolts on vw's, 27mm for some axle bolts, and 36mm for oil filter canister on vr6 vw's

 

[kiatech]

27mm on the 3.8L oil filter cartridges every day.

 

[hunterguy86]

36 mm for powerstroke oil and fuel filters as well

 

[Requin6]

Axle nuts, lug nuts, control arm fasteners, oxygen sensors, other suspension components.

This...

 

[wannab20hatch]

Biggest socket I have and use is 24mm. Odyssey/crv/pilot liftgate wiper motor/arm

Interesting. Sounds like those special Vise Pliers might be usefull. The ones with smooth jaws that grip the fastener on the sides.

 

[sberry]

It seems like I used a 32 for some reason the other day. I dont own every shape they ever invented of large metrics but have a cman set. In the end I wold consider them to be part of a complete set. The use is rare enough they dont ride on my service carts.

 

[amlv20]

21,22,24 on lug nuts. 36 on power stroke oil and fuel filters,24 on fuel filters. 24-36 on some euro oil filters.32 on echo tech oil filters and 6.7 ford fuel filter.24-28 on Toyota suspension. 21,24,28 on new electronic power steering racks.34-35 on f150 spindles. Diff pinion gear nuts, and other random suspension on the heavier trucks.o oo also very usful when pressing things together and installing random seals.

 

[NC-Fordguy]

30mm on toyota 8 axle pinion nut--same size on the output shafts on t-cases

 

[Fireball027]

I use alot of larger sockets on axle nuts, control arm bolts, my motorcycle swing arm, and other random stuff. I have a full set up to 38mm, and then some random one after that.

Even dodge trucks use a 43mm (i think) on the front axle.

 

[fitz11]

22 on modern motocross bikes front axles and 32 on the rear.

 

[Hammell]

33mm, track pads bolts on Cat d7H and D7R. Grader 140gr Wheel bolts. 28mm on D7H and D7R stump pans. Just a couple off the top of my head as I just worked on them a few weeks ago.

 

[redwrench60]

A guy I work with has a 94' Chevy pickup with an older set of custom wheels on it and the lug nuts for them are 20 mm. 19mm/3/4" is too small and 21mm/13/16" is too big. But 20mm fits perfectly.

 

[Applesauce]

What's the torque like for those nuts.? Can they be removed with a 10 or 12" adjustable ?

You could, I guess, and I certainly did in my own garage at seventeen...

The torque is generally very low, 25 Nm for a bolt that's effectively M24 or so. And they're invariably aluminum, lightweight, anodized, and in plain view of picky customers: poorly-fitting wrenches can be pretty hard on them, at least aesthetically. As Garboui noted, I had a machine shop remove the chamfers from the tops of sockets used for these fittings.

 

[dsmnickk90]

21mm, 22mm and 24mm all the time on suspension stuff. 28mm on some oil pressure switches
30mm 32mm 34mm 35mm and 36mm on axle nuts

 

[Dave455]

ISO metric standard sizes are 22, 24, 27 and 30 so those are fairly common on suspension components, sump plugs etc on Euopean and newer British vehicles. Even the humble Mini uses 32mm for hub nuts! You'll find them on machine tools too!

 

[mailpup]

I think I've seen this mentioned by someone in these forums before but I've come across a 23mm hex banjo bolt for oil cooler lines on a old 80's vintage Mazda RX-7 rotary engine.

Thats a odd one I dont think I have ever used my 20mm or 23mm

 

[mailpup]

Yes, it is odd. I bought the 1/2" drive 23mm Proto socket just for that application but I haven't used it since.

 

[R-C]

34mm 12pt 3/8dr on a Duramax crank bolt this morning

 

[75' forty]

I use a 54 mm on my front axle and a 46? on my crank pulley.

 

[Moose-LandTran]

Only time i can recall using a 23mm was on the lower control arm ball joint nuts on a Mazda 6.

 

[shampoop]

54MM for a 13b flywheel nut

And I agree with 21, 22, and 24 being very important to have, I have also been glad to have 27mm stuff every once and a while.

 

[KEH]

27 mm on some European farm machinery. Bought a Wright impact socket for those applications.

KEH

 

[Jason280]

I use some of the larger sockets quite a bit. 21mm for the lug nuts on the '07 Expedition, 36mm for the Ford 6.0L diesel fuel filter/water separator, 30mm for the drain plug on a Jeep NP231 transfer case, and I believe 21 or 23mm for frame/spring bolts on a Jeep YJ.
