Fits a variety of vintage Mercedes-Benz vehicles fitted with hubcap rims.  Each lug nut measures approximately 1.5" overall length..  These shorter lug nuts will be necessary if you're switching your vehicle from "bundt" style rims to wheels designed to accept painted hubcaps and will work with rims which are 13", 14" or 15" in diameter.   The lug nuts have an added galvanized coating extra moisture and weather resistance as well.
