Lock down your wheels with confidence. The Mishimoto Steel Locking Lug Nut 20-piece Kit features a one-piece design that eliminates the common failure points of two-piece lug nuts. Each lug nut is built from high-strength steel to resist swelling, cracking, and impact stress over time. This kit includes 16 standard lug nuts and 4 locking nuts, secured with a 7-point, non-marring locking tool to protect your wheels without damaging the finish. The 19mm hex size fits a wide range of aftermarket wheels, and the open-ended design accommodates extended studs. Available in black or silver, this kit is backed by the Mishimoto Lifetime Warranty to keep your wheels stylish and secure for the long run.
