E-Torx (External Torx) do you run into them?

E10 in 1/4 inch you can get from GearWrench, SK, Matco, VIM, Kobalt (I think) and some of the German brands. I'd like the SK set but they are pricey. I wish Tekton would make a decent set.

Where are you guys finding the e10 and e12 in 1/4" drive?

I just checked my set and my shallow and deep e10 and e12 are both 3/8" drive.

I got mine from proto, impact rated to match my gearwrench set. Pretty sure amazon sells them. Expensive, but you'll find using the 3/8 drive versions can be next to impossible.

A fair amount of torque can be applied using the hex equivalents, 6pt, 12pt or spline - 12pt better than 6pt, spline better than 12pt.

6mm for E8
5/16" (8mm) for E10
9mm for E11
3/8" for E12
7/16" (11mm) for E14
1/2" for E16
9/16" for E18
5/8" (16mm) for E20
3/4" (19mm) for E24

(Another good reason to not dump your old SAE tools :))

Vauxhall/opel as well. Had an late 80ies (I think) omega where the driveshaft and rear diff had those IIRC.

I bought a rebuilt 50DN alternator last year. The rebuilder used some E-Torx. I had to remove two bolts to attach a bracket so bought E-Torx socket from Harbor Freight.

On my last order to TOPTUL, which was a personal order for me and my friends, I ordered a box of the following E-torx impact sockets:https://www.toptul.com/en/product-346905/7PCS-1-2-inch-DR-Star-Impact-Socket-Rail-Set.html Since these came 10 in a box I've got seven left. If anybody is interested in buying one or more of these from me PM me. The cost will be $30 per set including shipping by Priority Mail which, considering the current state of the Post Office, will mean that you'll get it sometime within a month whereas it use to be two days.

I just purchased a Grey Pneumatic 1/4" drive, impact E10 socket.

The part # is 910ET.

Blarf, thanks for posting the list of tool manufacturers who make E10 and E12 in 1/4" drive. :beer:

I will be looking at Ko-ken and Proto (thanks 2ndGearRubber) in the near future.

1/4 drive e10 has been on my list for awhile, ran into a snag on an Astra oil pan, ended up using a coworker's 1/4-drive 5/16 12 point. Maybe I'll add 1/4 e12 to list as well

I saw a 1/4 e10 on the snap-on truck this week but held off because all my other e-sockets are matco and I can be OCD. Matco is probably cheaper too

Matco has a ratcheting e-torx wrench 4-5 pc. set that isn't too ridiculous in price, $120ish I think

....But the Craftsman display in Sears several years ago told me splines would work perfectly on just about anything :D

My Opel is riddled with them.
I bought multiple sets, 1/4, 3/8 and 1/2.

My Zafira from the year 2000 (Opel model) also has them. I have also met some in my brother's Mercedes. Class C 2004 I think I remember.

They seem like a great high-torque handling socket to fastener joint.....until they don't. I had one on my caliper bracket that had a nearly invisible bur that absolutely prevented the socket from even starting to go on.....I thought someone put the wrong size on it. With the angle, I couldn't' even tap/hammer it on.....had to use a mirror and a file and 10 minutes to remove the bur then all was well and it was like there was never a problem. With the size of the bur, if it was a hex, I fell like a socket would have slipped on it and the filling wouldn't have been necessary.

All those points of contact come with a price....the dimensional tolerance range between the two is smaller.

Curious where you found the conversion, I never successfully found a nice chart for this.

A fair amount of torque can be applied using the hex equivalents, 6pt, 12pt or spline - 12pt better than 6pt, spline better than 12pt.

6mm for E8
5/16" (8mm) for E10
9mm for E11
3/8" for E12
7/16" (11mm) for E14
1/2" for E16
9/16" for E18
5/8" (16mm) for E20
3/4" (19mm) for E24

I did the calculations my self - the fit is not perfect of course.
If you have spline sockets you might have to go one size smaller.

If anyone is looking for a resonably priced E12 1/4" drive socket, consider Grey Pneumatic.

I just bought one.

The part # is 912ET.

Mercedes has them sprinkled about. I bought a Husky set, but the drive sizes don't always match up great with the bolt size. For smaller sizes I've found that 6 point sockets work great and I can use a 1/4" drive ratchet instead of a 3/8.
