    Affordable Insurance. If you have a set of pristine factory rims or aftermarket wheels, a set of Six Spline Lug Nuts are a must-have for a peace of mind, as well as protection against theft. These black lug nuts features an unique 6 sided design that changes the look of your new wheels without stealing the show. At a fraction of the cost of some flashy lugs, they're a great choice.

    Designed for Security. These Black Lug Nuts are designed for maximum security with an unique six sided spline design. The kit includes a special six spline deep-socket adapter key that makes it nearly impossible to remove your wheels without it.

    6 Spline Adapter Key. The included Six Spline Lug Nut Adapter Key is forged out of chrome vanadium steel for strength. The key is compatible with a 3/4 in. or 13/16 in. socket, as well as the factory Mustang lug wrench.

    Application. This set of 20 Black Six Spline Lug Nuts are designed to fit 1979 to 2014 Ford Mustangs, including the LX, GT, V6, Bullitt, Mach 1, SVT Cobra and Shelby GT500 models. These lug nuts do not fit 2015-2016 model Mustangs as they use a different thread pitch.

    Is it ok to use an impact with these nuts and key? Obviously I'll use a torque wrench for re-installation, but I'm asking for removal.

    • The Black 6 Spline Lug Nuts can be used with an impact wrench, but care should be taken.

    I have american racing torque thrust classics on my 01 mustang staggered in 16x7 and 16x10 will these lug nuts work with my wheels?

    DavidW

    • We believe that the Black 6 Spline Lug Nuts will work with your wheels, however since we do not offer the American racing Torque Thrust wheels, we cannot confirm fitment.

    Will these work with velgen classic 5 wheels?

    • At this time, we do not carry the Velgen Classic 5 wheels, so we are unable to confirm fitment with the Black 6 Spline Lug Nuts.

    Will these work with Shelby SB201 20x10.50 wheel?

    CaseyO

    • The Black 6 Spline Lug Nuts are compatible with the Shelby SB201 wheels, and due to their low profile, are an excellent choice to avoid finish damage when installing/removing the wheels.

      Broke in half on the stud

      I bought these about a month ago and have only hand torqued them off my mustang 3 times the 4th time I went to take my wheels off the lug nut broke in half on the stud. There was nothing left for the key or a socket wrench to grab on to. My wheel was stuck on there until I finally drilled OUT the stud. I inspected all the lug nuts and it seemed as if all of them showed signs of twisting! Horrible product turned into a nightmare. Never have seen anything like this before wish I could rate 0 stars!

      No need for locking lugs with these!

      Replaced the factory lugs with these spline lugs which matched up nicely with my MMD wheels. I had them put on when I was having the oil changed. The tech was impressed and so was I. Would definitely recommend to anyone, especially if you have black wheels!

      These lugs fit inside the Mickey Thompson rims a lot better then the stock lugs. The stock lug wrench would not work with M/T rims. The spline lugs are small and are easer to put on and the key I can now use the stock lug wrench. would recommend for after market rims.

      Looks good

      They all fit perfectly and look really good on the stang. I like that each one needs the key to unlock. Just make sure the person putting them on doesnt go crazy with the air gun so they can last longer and not strip.

      Great improvement

      After buying and installing aftermarket wheels it became clear that I needed a smaller lug since the holes were smaller. This set works well as advertised.

      Small mod pays big dividends

      Perfect addition to my dark wheels. Smaller diameter helps eliminate damage to wheels when removing or installing the lug nuts. One of the last steps to eliminate all chrome from my car.
