Deep thin 8mm socket to remove nuts of air filter baffle on a MS261?

[1Alpha1]

I have a 1/4" nut driver set that has thin-wall sockets.

It comes in very handy at times.

The 6 in 1 screwdriver is 5/16" (0.3125") across the flats. 8 mm is 0.31" more or less. Socket applications generally work, but an 8mm hex key (Allen wrench) does not fit a 5/16" socket (3/8" socket head cap screw) well enough to work.

In a situation like this I would buy a cheap "donor" socket (if I didnt already have one).
Chuck it up in a cordless drill, either buy using your 1/4" extension or using a 1/4" drive adapter.
Than take it to your bench grinder and turn it down a little until it fits. (with your drive spinning slow so it removes the same amount of material all the way around)

Exactly what I did when I ran into this exact issue years ago with one of my 261's. Just got a cheap Chinese 1/4"bit socket and took it to the chain grinder and tuned it down. Not even my Wiha would fit. Not much room there!

They just can't make it easy.
My 8mm deep socket has a OD of 11.75mm. The hole is 11mm.
Where do I find a 8mm thin wall deep socket that has OD no more than 11mm?
Or how else do you even remove those two 8mm nuts? The workshop manual doesn't mention a special tool.

All you need is a nut drive. 8 mm or 5/16....
And if need, you can grind it down the OD to fit.
Good luck.

Assuming that there is an OEM STIHL service tool for this? Anyone have a photo of it, just for curiosity?
