Please ask more specific question. I do not know what you need. I will gladly answer all your questions. XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX I lost connection with chegg.com. I am repeating my question hoping that the expert I was working with will pick up my request.

How to calculate the torque necessary to get the required clamping force of a SS$304$ screw turned without lubrication into aluminum $6061-$T$6$ as a function of the screw OD and pitch.

Please ask more specific question to allow me to provide the proper information. Maybe a specific example will clear up the water. I would like to calculate how much torque I must apply to SS$304(18-8)$ screw M$3-0\mathrm{.}5$ turned into AL $6061-$T$6$ to get clamping force $2\mathrm{.}89$ Lb$.$ I would like to be able to expend the formula to other screw sizes.
