XTR Rear Freehub Bolt Torque

    I purchased an M9010 rear hub and I wish to remove the freehub body but when I looked at the Shimano tech-docs I noticed a number that just doesn't make sense to me.

    The freehub bolt is required to be torqued to 150 Nm. Is it just me or it that an insane amount of torque for such a small bolt? I work on cars in my spare time and I recently changed front wheel bearings on a Toyota Yaris and the hub nut required a torque of 172 Nm to adjust the bearing preload. The nut was either a 30mm or 32mm 12 sided piece with a very fine thread pitch. I understand this requiring such torque but a freehub bolt on a bicycle?

    I have a 1/2 inch S/O torque wrench with a 15mm hex key so I have the tools but I am afraid to tighten the freehub to this figure. Please find the attached document on page 24 if in doubt:

    If the threads strip will Shimano cover it, I doubt it?

    Just do it up to FT torque and don't worry about it.

    Appears to be a good idea.
