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.

Dual-Drive Phillips Bit Socket Sets

When vertical space is tight or you need an extra twist on your socket, use one of the dual-drive Phillips bit sockets in this set. They work with a standard square-drive tool and a box or open-end wrench. Tighten them with your square-drive tool and give them an additional turn with the leverage from your open-end or box wrench. Or just use a box or open-end wrench when you can’t fit your square-drive tool. Pair them with hand-drive tools only. The sockets in these sets come with a clip rail to make sure they stay put and organized when not in use.
