The boundary condition on the left (i.e. at the center axis of the bolt) should be constrained in the x direction due to symmetry (in a bolt, it'll have the same force pushing opposite in the x-direction from the other side, canceling out virtually exactly) instead of bulging out as is shown. (Not that it changes your observations really.)
