The SK Hand Tool 85790 1″ Drive 6 Point Deep Budd Wheel Impact Socket 1-1/4″ is a heavy-duty impact socket that is specifically designed for automotive applications. It is made in the USA and features SK’s SureGrip hex design, which drives the side of the hex, not the corner. This not only provides increased strength, but also avoids the rounding of rusted or damaged fasteners, which can occur when using a sharp cornered hex tool. The socket also features an improved black coating that retains more rust preventative compound than black oxide.
