The GEARWRENCH Bolt Biter Lug Nut Extraction Sockets are designed to remove worn or damaged lug nuts. The sockets feature a tapered entry that makes it easy to seat on a damaged fastener without hammering, and the minus-sized sockets are designed to grip lug nuts that are worn down substantially. The bidirectional design allows technicians to not only remove fasteners but to reuse them as well. The sockets also have a deep design and square drive with a hex base. They are made from chrome molybdenum and have a black oxide finish for corrosion resistance.
