9mm wrench/socket size. Any use at all?

[TCJ1981]

Looking over and cleaning up my tools the other day and noticed that all of my 9mm wrenches/sockets have had zero use. I've worked on alot of domestic and asian stuff and never have found a use. Is this a european thing or am I the only one wondering why they ever bother to make this size at all?

 

[sko]

you need to have it because the 8 would look awkward next to the 10

 

[Goinlow]

To be honest ic ant think of a use off the top of my head...

It's not an everyday tool for me but once a week.

When a 10 or 3/8th's head is fubared tap a 9 on problem solved.

 

[Stick Figure]

I've seen some hardware out of Australia that used 9mm nuts on a m6 x1.0 bolt. Normally these are a 10mm head size. That's about the only time i've reached for one.

Guess none of you have worked on any late model Fords.

I've used 9mm hex drivers on fords but i can't think of 9mm hex head bolts or nuts.

 

[Autoguy]

Metric sizes are more than their fraction counterpart , some are ther just to complete the set

 

[londonsteve]

A lot of mobility scooters out of Taiwan use 9mm nuts, Sad but true.

 

[wesmamyke]

Lots of bicycles use 9mm nuts on the brakes and derailleurs.

 

[mrholeshot]

I have a small box filled with 9mm wrenches. I didn't want to waste room in my wrench racks.

 

[spongerich]

Dirt bikes and quads have plenty of them. It's the 15mm ones that are completely worthless.

15 is one of my most common used. I guess it all about what you work on

No GM cars/trucks in your driveway? 10mm-15mm are the most common fasteners under the hoods of my Sierra and Astro as well as my kid's Pontiac.

Ford like's 15's too.

 

[nismomans13]

I have t bolt clamps on my intercooler piping that use 9mm nuts. I only remember it because i grabbed an 8mm and it was to small so i went right to the 10mm and it was to big and i thought wtf....9mm

 

[Moose-LandTran]

VAG clutch pressure plate bolts - 9mm 12-point.

 

[speed bump]

Honda bike brake bleeders are 9mm. I used it once on something else to.

GM uses Metric fasteners now?

The last GM car I had was a '70 Chevelle and I don't recall seeing any metric bolts on it.

+1 my gary fisher has a 9mm on the cable hold down nut

I've encountered 9mm before, although I can't think off the top of my head where. The size I've NEVER used on ANYTHING I've worked on is 16mm.

I guess you've never worked on much European stuff. 16mm is one of my most-used sizes.

 

[2chipped]

9mm hex are used to hold the back glass in ford trucks

Later model Fords use 16mm. My Expedition has several of them, including the oil pan drain plug bolt.

Yeah, hard as it is to believe. My old Chevy's mostly 1/2"-9/16" like yours. Afraid those days are over.

 

[wafrederick]

I use a 5/8 on a 16mm most of the time,same size.I also use 5/16 on 8mm headed bolts also,same size too.I pound on 9mm 6 point sockets on badly rounded off 10mm headed bolts.GM,Ford and Chrysler use 18mm also.

 

[hilld]

9mm are used on some German car brake bleeder valves, such as BMW and VW/Audi, but not all of them. I even have a 6pt version of one, for just this reason, but doesn't get used much.

 

[blarf]

I used it maybe once on the Volvo (for an e-torx screw I think), and about as often on the BMW. But it was one of those things that was annoying to have to seek out when I did need it.

GM uses it a fair amount.

Here's what's the point of a 20mm socket?

I've used my 20mm half in deep impact for 1 purpose, f'ed up lug nuts, either a 19mm chrome capped lug where the 19 would get stuck on every lug torquing them, or rusted to the point where the socket bite's the lug and gets stuck, or once or twice beating it onto a round head wheel lock key.

corner lens on crown vic comes to mind

 

[wafrederick]

An use of a 20mm wrench is on GM fuel filters,a 13/16" wrench will fit sloppy.I have a flip socket,19.5 mm x 18.5mm just for screwed up chrome cap lugnuts I bought from my Matco dealer and it does work.

 

[Bran Diezel]

i use 20 on swelled 19s all day long. i need a 23 for the lugs on those honda odesseys after they get some miles

 

[00S4Boy]

Wait are ram lugs 15/16ths or 23mm's?

Yeah, that's about the only time I use a 20mm also. Although a 13/16" should give you enough hold to break it loose, if the last person hasn't tightened it way too tight.

 

[Moose-LandTran]

9mm hex drivers are used on rear brakes of BMW X5s (new shape) some Mercedes-Benz and new VW Transporter vans.

Quite a few 8mm when you get into taking the intake manifold off of 5.3 motors.

 

[mooman]

I believe 9mm was the size head of the screws that held in my AC Blend Door Acuator Motor in my 04 Silverado. That job sucked!!!

 

[mtkst19]

i think 9 an 11 is european only, lol. my friend owned a pretty prominent tuner shop in the area. i would laugh at how he would either toss away the 9's and 11's or use them to make other tools because in his mind he would never use them. he always sub'd out the german work to me. what sucked though is i would have to drag tools to his shop if i did work there b/c he tossed all the sizes i would need. being a jap shop, they never touched 9/11/13/16/18.


one thing i wonder if there is a use for is a 9mm allen. i use 4/5/6/7/8/10 regularly and even bigger sizes for drain plugs or axles. Yet i never bought a 9 because never ran into a use.
