    If not, you gotta try a stud extractor, but I always liked the torx first, as a stud extractor gives a second "go".
    Good luck
    Snap On has these neat mulitspline extractors, they engage the full length of the drilled hole and don't taper to cause a wedge effect to make the bolt tighter.

    Those look like the Ridgid extractors I've got. My favorite kind of extractor, bar none.

    I would maybe negotiate a substantial discount on the next batch of parts. They may give you $1000 credit or more possibly? Still have to fix the part but at least you are getting paid to fix it in a round about way.
    What's a C.A.R.?

    Will adding to the stud with TIG work? Build it up to something you can grab? I have had good success with that method. The intense heat helps a lot too. Just be very careful with what you used for penetrating oil/solvent. You will need real good ventilation for this.

    Someone at the anodize shop knows exactly what the stud is made of and the circumstances that resulted in the breakage.
    Wouldn't hurt to just ask.

    Stud might still be laying around.

    If you do not know you are not playing in the game.
    Correction Action Report. Very basic in QC.
    If you don't have this down there is no sense asking for your six-sigma measuring.
