      Designed for Security. These black lug nuts are designed for maximum security, featuring a deep socket style key that makes it nearly impossible to remove your wheels without it. The kit includes an adapter that makes the locks compatible with your factory Mustang lug wrench.

        Black Lug Nuts

        These are as advertised and a great price!. No issues. I don't understand why Ford installs chrome lug nuts on black wheels. Simple changes make a huge difference.

        Reliable Lugnuts

        Can't go wrong with these lug nuts, they'll fit the majority of your aftermarket wheels. Would definitely buy them again if black ones come back in stock soon

        Well crafted But!

        Quick Delivery! Finely Crafted and the Finish was flawless!! The 6 Spline socked that shipped with the Lug bolts fit perfectly! But I had to return them because they don’t fit with the 2019 Stock rims I recently added to my 2016 Mustang GT ! And the Return Process was a Breeze!

        Great accent fo Black wheels

        These Black 6 Spline Lug Nuts are the perfect accent for the Black 20" wheels on my 2016 Black Mustang convertible. The spline lugs will also help deter theft by making it less convenient for a regular lug wrench to fit. These black lug nuts pull the whole look together and look much better than the contrasting chrome ones. I recommend this Black 6 Spline Lug Nut Kit to everyone with Black wheels to give them a completed look.

      do these fit oem and aftermarket wheels with no issues, I'm buying Shelby sb201 wheels, will these work perfectly with these wheels, thanks

      • The Chrome 6 Spline Lug Nut Kit should have no issues working with the Shelby SB201 Wheels, and due to their low profile, prevent scratching of the wheel.

      Are these the lugs you would use with the RTR 20" tech 5 wheels? Thanks

      • Yes, these would be a great fit with the RTR wheels.

      The conical seat appears to be smaller than the conical seat on the oem lug nuts. Are these safe to use if the seat is smaller and won't come into contact with the entire mating surface on the wheel.

      • The 6 Spline Lug Nuts we offer will have a smaller conical base that your original OEM lug nuts. However, this will not cause any safety concerns as long as the lugs are torqued down to the manufacture specified foot pound.

      Are these lug nuts a single solid piece? Or do they have the two piece design like the factory nuts? I am tired of stripping off the two piece lug nuts and having to replace them.

      • The Chrome 6 Spline Lug Nuts will be a one piece lug nut.

      Would these work with Enkei PF01 wheels?

      • While we have not tested these with those wheels, This set of 20 black 6 Spline Lug Nuts will fit all 2015-2019 Ford Mustangs, including the V6, EcoBoost and GT models.
