Each bolt has ultimate load, you can find it in standard for your bolt.
About tensile load in bolt:
I don`t familiar with SW simulation but if SW has several loads to output, you can find out wich one is total because you deal with very simple example.
Thank you for this guys. I found some more informations. According to link below Solidworks checks maximum of two: preload and load comming from simulation.
So I tried two simulation. First one is just tightening (no external forces). Result? 5208N axial force.
Second one is a 100kN tension force applied to one of the faces (see picture) and 0Nm torque. Result? 170N axial force.
Well, for me it is not right. How is this possible that using 100kN tension force I get only 170N axial force in bolt?
As you can see from picture bolt does not stretch.
Your first model was OK for pretension problem. Parts was in tight contact. But this second model looks wrong because there is no tight contact between parts. Where are parts which are pretensioned. I don`t see them. How are they constrained. Solve the simplest case - without pretension stage.
