McGard black duplex cone-seat wheel lock set (9/16-18 thread) — extended-length duplex locks in a four-piece kit with one key. These locks act like standard lug nuts but require the special key to remove, helping protect wheels from theft on deeper or duplex-style wheels. McGard machines locks from restricted-chemistry steel and through-hardens them; the black finish uses PVD over multilayer plating for long-lasting corrosion resistance.
