It's made from grade C steel and features a flanged head and prevailing torque locking mechanism to resist loosening from vibration. You typically replace this nut when servicing torque rod bushings, U-bolts, or if you notice loose suspension hardware, because reusing old lock nuts can compromise clamping force and safety.
