I have created a fastener in an assembly and ran the static analysis. I got the output of the shear force and Axial force as follows.

Fastener1_axial_stress: 3.026563e+03
Fastener1_bending_moment: 8.841788e+06
Fastener1_bending_stress: 6.871864e+03
Fastener1_shear_force: 1.125990e+05
Fastener1_shear_stress: 2.579097e+02
Fastener1_torsion_moment: 7.846665e+02
Fastener1_torsion_stress: 3.049226e-01

Fastener shear force value I want to know which plane force is that. If we do beam or spring approach we get the Shear in Plane 1 and Plane 2. But here shear force on the fastener is only one value. How to understand this ?

"...The fix separation option for the fastener is preventing the parts from
separating at locations where they should separate. Hence, the results
for this analysis may be inaccurate. You should turn off the fix separation
option for the fastener and, if desired, introduce a contact interface
between the parts that are connected by the fastener..."

-> I have tested a lot: without contacts the bolt forces are not ok...
