Includes 20 black lug nuts and a special key adapter tool to prevent wheel damage and deter theft. ## Description Circuit Performance 7 Point Star Spline Drive Lug Nuts are the perfect way to finish your new wheel installation. The ultra-thin design is ideal for smaller diameter lug holes found on aftermarket wheels. The 7 star spline pattern provides maximum gripping power and resists stripping. Circuit star spline lug nuts feature a closed-end design. Perfect for your new set of aftermarket aluminum or steel wheels. Don't risk scratching your new wheels! The thin walled key adapter tool (included) protects the wheel's surface, and also adds an additional layer of security, deterring would-be wheel thieves. Unlike standard spline drive lug nuts that are produced by dozens of different companies, Circuit Performance Star Spline drive lug nuts are a unique design that is much more secure. The Star Spline tool is required to install and remove the lug nuts so thieves will have a much harder time trying to steal your new wheels. Unlike standard spline drive tools that can fail with very little torque applied, this new design also allow far more torque to be applied to the lug nut before the tool fails. You can be sure that with Circuit Performance you are getting the highest quality.
