External Torx-Plus Socket Sets

With squared lobes that won’t slip at high torque, all of the sockets in these sets are designed to fit on external Torx-Plus fasteners, often found on pickup trucks. They’re machined to tight tolerances and made in the U.S, which means they have a firm grip and stand up to tough jobs for a long time. Attach them to ratchet wrenches and other square drive tools.
