Talk about versatile! Two stylish 1/2” Drive impact flip sockets in one set. Made to fit the most popular sizes of SAE and metric lug nuts, these sockets can be flipped from a smaller size opening on one end to a larger size opening on the other, depending on your needs. Built of strong premium chromoly steel with a beautiful stealth black phosphate finish, theses sockets have thick walls that pass torque wind-up from the impact tool to the fastener with maximum power and minimum drama. The high contrast size markings won’t wear off so finding the right socket end is easy. Inside, our innovative Z-Drive design helps sockets get a better grip by turning fasteners by their sides, not their corners, giving you more control and reducing slippage at high torque loads. Precision chamfered openings make it easier to slide the sockets over fasteners. Dependable Powerbuilt sockets meet or exceed ANSI standards and have a lifetime warranty, all at affordable prices.
