like TooManyMBZ said, try heat. Ive used it on pesky door strikers that even with the correct size Phillips driver I knew I'd strip the head off. . . a $35 heat gun is a wise investment. . it is amazing how after 30 or so years these bolts can become stuck so hard. Get a heat gun, be certain not to accidentally ignite any surround surfaces and apply heat in 30 second intervals until the little fu*ker is ready to come out. . .

EDIT: I meant, some of the best tools you could get if you weren't in the market for the highest-up, extreme, "professional" stuff. For the average homeowner, and DIY customer, Craftsman used to be awfully nice stuff.
I still like craftman tools for 95% of everything I do, just not their allen wrenches. I used to work in a tool and die shop which uses nothing but allens. You get spoiled when you have the good ones.

but I don't. lucky me, the transmission seal doesn't leak and the disc is only just starting to crack a little. good for another 50k I presume. and by then the 280 tranny will go in:D. plenty of those where this car is going...
DO NOT WAIT ON THAT FLEX DISC.

I see no other option than to install another transmission. I have no airtools. No welder. I'm sure it'll hold for 50k more. they're pretty tough. and what's it gonna do? 'destroy my tranny'? that would make me cry, a destroyed automatic transmission:D

No, it will destroy the underside of your car.

no ****! that's some damage right there. wasn't there an audible warning beforehand though? was this specimen "lady driven, with ipod"?
I mean, dude! well I guess I'll go in there again then. the allen bolt is nearly stripped. it was as tough as the craftman key I used almost, so they got damaged equally. I'm guessing a good allen key and airgun can still take it out. I have a friend with the tool... not the allen though, I'll buy that off a snap on truck.

99.9% of all my tools are craftsman.

MIne have been very very good. Most were purchased a good while back though.

Once you've made certain the hole is clean, try dipping the tip into some Comet/Zano/etc. cleaner - it helps to give you a little extra grip. (unless you have valve grinding compound, as Dubyagee suggested).

I am not sure which model Mercedes you are working on. But if there are nuts on the other end of those allen blots (if there is room for it) you could split the nuts with a Nut Slpitter or split the nuts with a good quality sharp chisel. Another option would be to grind a split in the nut with a small 1/8" rotary file. This would work best with a Dremel type tool because they have a higher speed than a Electric Drill.

I'm not sure, that is not my car, but I have seen pictures of several failures and the aftermath always looks like that.

couldn't he get a killer grip on the head with a pair of locking vice grips... i mean the kind of force that it takes a pair of channel locks to get the vice grips back of the head they were locked so tight?

that should get him the leverage he needs to turn the other side with a wrench.. i know when i replaced my flex disks the bolts on there seemed to be one way... they went on easy but stripped when you tried to take them off... and man did those things heat up even with hand tools.

Henry,

Most of my tools are craftsman, and the only time I have rounded out an allen bolt is when I turned it the wrong way thinking I was loosening it....when in fact I was tightening, and then stripping it. :o It was a motor mount bolt, and its still on the car (83SD)....I'll be hammering a torx into it sometime in the near future when we replace the mounts probably. :o Not looking forward to trying to get that out.

If it was anything like what I had to do, get a 12 point socket just smaller than the head of the bolt, put it on an extension, and pound that SOB with a decently weighted hammer...
