What does my bolt torque to?

We get a lot of "what does xxxx torque to?" questions. A lot of the fasteners do not list specific torques in the service manual. Here is a basic bolt (not stud) torque recommendation chart from Yanmar. The list shows Grade 4 & Grade 7 bolts screwing into both cast iron pieces and aluminum pieces.

NOTE- This is just a general guide! always use the torques shown in your specific model's manual if they vary from this chart. These recommendations do not apply to head bolts or other special fasteners. The size listed is the thread size - not the head size or the wrench size.
