Wave-Type Locking Lug Nut...
'Just stumbled on one of my eight (maybe more) "locking" lug collection. Pardon Hurricane Irma's rust that obscures the full depth of the "wave" pattern. Although the "wave" appears symmetrical, it is not.
The "wave" pattern in the four provided lugs has a single matching "key"—unique to the set. The key, with its matching wave has to be carefully matched to the lug nut, which then can be put in a wrench to remove the lug nut and tire.
