The box end of the Stanley® Combination wrench employs the Max-Drive™ system, which allows the box end to contact the fastener away from the corner. This system allows 15% more torque to be applied to the fastener and helps reduce fastener rounding. Stanley wrenches are designed to meet or exceed ANSI specifications.
