McGard cone-seat wheel lock set for under-hub-cap applications (1/2-20 thread). This four-piece kit includes four one-piece locks and a unique key; they fit and function like regular lug nuts but require the special key to remove, deterring theft. McGard manufactures locks in the USA, fully machined from restricted-chemistry steel and through-hardened, with computer-generated key patterns and optional caps for exposed use.
