Abstract
A ratchet wrench has a drive-stud element with a drive stud at a first end and a drive recess at a second end. The drive-stud element is coupled with a one-way drive transmitting wheel to rotate in unison therewith about an axis. The wrench can have a centering element that resists movement of the one-way drive transmitting wheel in at least one direction away from the axis. The drive-stud element and the one-way drive transmitting wheel can be separately formed. A method is also disclosed for operating a ratchet wrench with a drive-stud element with a drive stud at a first end and a drive recess at a second end.
