On a box end wrench, the head of the tool is completely enclosed for maximum gripping power. The resulting maximum torque action is preferred for loosening very tight fasteners and for use during final tightening operation. Box end wrenches are usually available in 6 point (6 interior corners) sizes for tough-to-remove fasteners and 12 point sizes for areas where there is less space or arc to move the wrench.
