Torque to force relation

Hi there:

Im trying to determine the force to torque relationship for a bolted surface. This surface should maintain a certain pressure (e.g. 8000 psi). Usually 4 bolts are used, so i determined the axial force needed from each bolt. My problem is how to determine how much torque needed to reach that axial force. I have found T=K*D*F and also another equation used in power screws that involves picth angles. I would apreciate any help with this.

Also bolt material is stronger that taped surface (Bolt= Stainless steal 35 ksi; Surface: Aluminum T6-6061 32 ksi) can I make the same analysis on the aluminum as the one i used for the bolt?

Thanks

Rudy

The following threads should be useful for your analysis:

Thread288-20937, Thread725-22078, Thread727-22951, and Thread288-21503

The analysis should be for the entire joint, not a separate one for each component (bolt, Al part, etc.). The best system is that described in VDI 2230.
