Team Associated Factory Team 4mm Low Profile Serrated Wheel Nuts are designed to fit on the front of cars that require a thin nut to maintain the legal width limit at major events (example: B74, B64, TLR 22, TLR 22-4, Tekno EB410, Yokomo YZ-4 SF). These nuts feature large-diameter locking serrations that "bite" into the face of the wheel, providing a secure hold in demanding conditions.
