Shop ET Style Conical Seat Lug Nuts
Specifically designed for ET wheels, but also used for the purpose of perfectly centering the wheel around the lug hole, which allows for a lug-centric wheel fitment. They also feature a "bulge" at the tapper to allow for greater seating engagement. NOTE - can only be used with wheels with properly-drilled ET lug holes, can be used with Topline Washers Part #C785 or C786
