Taper pin/split pin/collar?

Generally we provide taper pin/split pin to restrict axial movement but why do we use collar and then insert these pins instead of inserting it directly into the component??

    You should typically use the collar so the component is free to move or rotate. It is also possible the component lacks the strength to resist axial movement if pinned. The collar can be made stronger to account for the component's lack of strength.

    The collar provides additional strength to the mechanism.
