The impact socket set features a 6-point, high-torque design that contacts and grips the stronger flat sides of the nut or bolt head, not the weaker corners, preventing stripping or rounding off under high stress. It also comes with a special customized case to provide you easier storage. This effort-saving 1/2 drive deep impact socket set comes with 19 impact drive sockets. The 6-point socket design grips the flat sides of fasteners rather than the corners to offer security and prevent stripping and rounding off bolt corners. Our extra-large size markings are permanently etched onto our every socket, so, even in low light, you don’t have to waste a lot of time identifying the size you need. This socket set is ideal for removing and installing wheel lug nuts, particularly suitable for most trucks, RVs, and other heavy-duty vehicles.
