Dear Hassan

I consider 2 options for this shaft.

1- It is not a load bearing designed member. Then you dont need to consider it in your calculations. It is for mounting purposes.

2- It can be designed to reduce the shear applied to the bolts and then the bolts can be designed essentially to carry the overall moment.
