      Affordable Insurance. Whether you have mint factory rims or sleek aftermarket wheels, a set of six spline lug nuts are a must-have for peace of mind and as protection against theft.

      Stealthy Black Finish. These premium quality lug nuts have a durable black finish that enhances the look of your new wheels but doesn't steal the show. And at a fraction of the cost of some other flashy lugs, they're a smart choice.

        Black lug nuts

        They look great and add security, since you need the special socket that comes with them.

        Lug Nuts

        Not much to say. No one will take them off your car with a 4 way since they are 6 spline.

        Great way to hide your lugs

        These black lug nuts are great for rims that are black around the lug holes. The lugs look better than chrome lugs.

        so I goofed...

        ...I bought some new gt500 replica wheels during the traditional AM Christmas/end-of-year-blowout sale ($80/per wheel, can't beat that)...added the wheels to my cart and checked out...didn't even notice the note/warning stating stock lugs wouldn't work...oops! Anyway, ordered this set, came in quick (as usual) and they worked like a charm. They're lug nuts, what else can you say about them LOL...they seem pretty resistant to scratching so far, time will tell! (note: these lugs actually went on my 2010 Crown Victoria, not on any of my Mustangs, but I wouldn't hesitate to use them on any of them).

      I bought a car with these lug nut but they didn't offer/include the adapter. Do you see just the adapter?

      • I apologize, we do not carry the adapter separate from the kit.

      Will these fit a Mach 1? The factory Mach 1 lug nuts are longer than average, and the local auto parts store splined lug nuts will not work. They are too short and run out of thread before they tighten down on the wheel.

      • These will indeed work with 03-04 Mach 1's.
