Kraton Stripped screw, speed out extractor didn't work

[REDACTED]

Glad to hear it is solved!
Myself, I've been on a brink of stripping some bolts as well.

Here is what I did: got Wera 354 series hex drivers for the sizes I need. Pretty cheap. They are marketed as having a slightly larger contact surface: "Hex-Plus offers larger contact surfaces in the screw head."

And the most important part: I plan to only use them on the loctite bolts to make sure this set of drivers stays fresh. Hopefully this strategy works. If not, will see you here )

That's a great strategy. Thanks!

This troublesome little fella is going into the aluminum stand offs of the servo mount on my kraton 6s exb.

Just performed the exact same procedure a couple weeks ago. Them screws is thread locked. PIA! Drill the head off as others have suggested, once the aluminum standoff is loose, use a propane torch or similar to heat, then pliers to remove what’s left of the screw. I clamped the standoff in a vise.
