So it can sit squarely on the nut, but you won't skin your knuckles turning it.
The hexagonal head is easy for a spanner/wrench to get a firm hold on.
A socket wrench can drive sockets that totally encompass a nut or bolt head, thus getting a much better grip of it than a wrench.

The pipe wrench (in the US), Stillson wrench or Stillsons (inthe UK) is an adjustable wrench used for turning soft iron pipes and fittings with a rounded surface. The design of the adjustable jaw allows it to lock in the diametre frame, in such away that any forward pressure on the handle tends to pull the jaws tighter together. Teeth angled in the direction of turn dig into the soft pipe. They are not intended for use on hardened steel hex nuts or other fittings because they would ruin the the flats cut on to the head. However, if a hex nut is soft enough that it becomes rounded beyond use with standard wrenches, a pipe wrench is sometimes used to break the bolt or nut free of its position
