Abstract
An improved box end has substantially no projected manipulation element in a trigger member. A channel in the head is in communication with a central opening with a notched member disposed therein and a slope between the head and the handle. The manipulation element is clockwise or counterclockwise rotatable in a distance defined by the width of channel for moving a spring-loaded steel ball from one slot to the other slot of a follower coupled between trigger member and notched member, thereby adjusting the position of notched member for aligning with an object to be held. Further, this wrench is sightly.
