Defining Torque for Different Parts

Are you speaking about a torque being applied to the joint itself, or about the torque applied to the bolts that may be part of the joint?

As for the main parts, the torques they exert on each other are equal, but in opposite directions of rotation.

Hello Guest,

Are these joints critical? Could the loss of joint integrity result in loss of production, property or even life? If your answer is "yes", this is the proper way to define torque:

1. Analyze your joint to determine the required clamp load
2. Calculate bolt elongation at that clamp load
3. Take a wild-a** guess at what the friction factor might be
4. Use the above answer to calculate a torque figure
   
5. Specify this torque value along with the required clamp load and bolt elongation
6. Provide a bold warning to state that the specified torque will likely not result in the desired clamp load (Why not? Look here)
7. State that bolt elongation should be measured while "torquing"
8. State that the specified torque is only to be used as a general target in order to achieve the required elongation
9. Specify that a record of all bolt elongations is to be maintained for QA management purposes
