Our Summit® lug nuts are more than good looking--they're made from high-quality steel for reliability. These nuts are tested for hardness, thread accuracy, and overall quality, and are then given a final visual inspection before they go out the door.
Warranty
Due to the many wheel styles and fasteners available, it is the installer's ultimate responsibility to verify that the correct fastener style, thread size, length and seating surface (flat seat, conical seat, radius seat, shank style, conical seat with shank, etc.) as recommended by the wheel manufacturer. Minimum thread engagement must be equal to the thread diameter of the wheel stud or lug bolt.
