Impact socket are mainly used in automotive servicing and general auto repairs where there is limited space to work and torque requirements are not very high
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
