The open end of an open-ended spanner fits over the parallel, opposite sides of a hexagonal or square nut or bolt head with very little play.
An open-ended spanner is made for a specific nut or bolt size and the risk of damaging the bolt or nut is small because the leverage length is matched to the size of the bolt or nut.

A ring spanner uses all the corners of a nut or bolt head.
The ring-shaped jaw surrounds a nut or bolt head around its entire circumference and engages on all six corners. As a result, more force can often be applied than with an open-ended spanner, which engages on only two corners.
The advantage of this is that a nut or bolt head can be turned in a confined space with only a small turning stroke.
