Combination wrenches feature two same-size openings; the open-end allows you to quickly apply low torque and the box-end allows you to apply final and greater torque
The opening angle allows two actionable positions, reducing the recovery angle to 15°
Box-end: 30° recovery angle
Open-end: 15° recovery angle
The openings are machined to precision for a perfect fit with nuts and bolts
