Default Complete list of bolt sizes in Subarus

I'm trying to find a list that has all the sizes of bolts used on a Subaru. And yes, I will be getting to every bolt one day or another

So far I know:

10mm
12mm
13mm
14mm
17mm
19mm
21mm
22mm
27mm?
32mm

There might be a 30mm, on a axle nut?

Edit: Note that these are referred to head size.

Anyone have anymore ideas, or corrections?

Thanks,

-paK +12

05+ WRX transmission bolt is a T70. While I applaud your moxie, this could be a BIG project. I started a Torque FAQ once with the torque specs........I got a day into it and had a huge, huge list that eventually crushed my will power to type.

- Una bows down to Subaru bolts.

Don't blame you though; I would've lasted till the idea of doing it. Wouldn't have even made it to typing the list out...

I'm fairly positive there's some bolts that need an 8mm wrench. And I assume you are talking about wrench (head) sizes, because bolts are usually measured by their shaft diameter so it's 6mm bolts that have 10mm heads.

Correct. As you mean such as a 14mm head corresponds to a 8mm diameter? I should note that.

Much thanks,

IIRC the exhaust bolts that have 14mm heads are M10s. The head size is sometimes unrelated to the actual size of the bolt though (hehe I said head size).

This project you are trying to start is exceedingly difficult. Good luck.

Ooohhh.....big task. It would probably be best to also include thread pitches as well as lengths since some are odd sized that must be ordered if you want to get replacements.

My workplace has ironically ordered quite a few Subaru-compatable nuts/bolts as of late....

I'm guessing you just want to have a known-sufficient set of sockets or something that can do anything on the car? Sounds like a worthy cause.

What on the car is 13mm and 27mm?

I believe the rear differential's drain and fill plugs take 13mm square keys.

The clutch fork rod in the transmission takes a 10mm allen key.

It's setup for a 1/2" rachet.

Are you positive it's 1/2" and not 13mm? The difference is a scant 0.3 mm.

Some bracket bolts under the headliner. It's hard to believe when I first encountered it, but the 13mm fit best. But I don't think anything engine related has 13mm headsize bolts.

27mm had a (?) mark to it since I wasn't sure, but had some thought of it.

If you want to buy another tool go ahead, but a 1/2" wrench fits perfectly.

There is definitely several 8mm, transmission ground wire @ firewall, and some trim screws.

i wouldnt say it fits "perfectly". yes its a good enough fit to get the job done. i always use my 1/2" drive breaker bar. however... its still a very loose fit and if the bolt was in there really tight you might have problems and/or cause some damage.

Are you saying an 8mm bolt size or head?

I've done many trannmissions (both MT and AT) removal related stuff and I've only seen 10mm head on the ground wire to firewall.

A lot of the hose clamps under the hood have 8mm heads on them.

And I do recall some of the mud flap screws on a 1st-generation Legacy having 8mm heads.

Hmmm.....You may be right, I was thinking head (wrench) size. Maybe it was a 10. I do remember that the upper left light trim screw was an 8mm (cause I used it to pull the throwout bearing pivot, and forgot to tighten it when I stuck it back in!)

The bleeder screws on the Brembo's are 11mm. I couldn't believe it. Took me 15 minutes to find the damn thing.

The screws holding the IC shroud to the hood are 8mm heads IIRC.
