The OEMTOOLS Locking Lug Master Key Set, No. 24447, is designed to remove locking lug nuts on most aftermarket wheels. This set offers thin wall sockets and extra-long lug keys to help prevent damage or scratching of the wheels and lugs. The double hex-head design fits most lug wrenches, as well as 13/16" and 7/8" sockets. The keys are made of chrome vanadium steel, finished with black oxide and stored in a blow molded case.
