10mm Hanger bolt spec?

Cb750 K5
Engine hanger bolts on the torque spec sheet is for the 12mm. I think it would be to much torque for the two 10mm hanger bolts. The ones that are long. Anyone know what they should be?

I have Hondamans comment in that post saved to favorites in photos and use it regularly. Along with torque sheets from a couple different manual iterations. So good suggestion!

I think the engine bolts in Hondamans comments are case bolts in this instance and not hanger bolts, but I could be wrong.

I torqued the two 10mm longer hanger bolts to 25ft lbs and the 12mm hanger bolt to 45ft lbs. hoping someone will correct me if I should take those 10mm up more.

25ft lbs and the 12mm hanger bolt to 45ft lbs is fine.
