Toplilne Premium Chrome Spline lug nuts are next evolution in chrome quality. Our Premium Chrome Spline Lug Nuts feature a triple nickel chrome plating process, and exceed a 48 hour salt spray test, for maximum prevention of rust or corrosion. Additionally, these lugs are cold forged and case hardened theat treated for best-in-class hardness, and utilize a 6-point spline for fitment on small diameter lug pockets.
