Do you put transit bolts back on when moving washing machine?

We bought a new washing machine and after taking off the transit bolts, the instructions states that you should keep them and put them back on when you move house.

I have never done this before when I move house and can't remember having a problem. Do you bother putting the transit bolts back on when you move house?

I am uncertain if I should keep the bolts and put them back on when we move house.
