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.

Great lugs!

Good replacement if your constantly changing wheels and tired of the junky acorn nuts that are so prone to stripping.

Will these little nuts work with the niche Milan 19 inch ??

Will these work with RTR Tech 7 wheels (on a 2008 GT)?


  • With the RTR wheels, you will need to purchase kit #390741 ( as those lug nuts have a thinner width than these lug nuts. The RTR wheels will require thinner lug nuts for proper installation and use.

Is there a way for me to get a replacement socket? I got rear ended and the body shop had to take off the back wheel for part of the repair and I guess they never put the socket back in the glove compartment. 3 months later I'm ready to get new tires and I realize the socket isn't there. The shop says they don't remember/aren't responsible.


  • Hello! We do not sell the lug nut socket separately but it is available online. Just punch in "6 Spline Lug Nut Socket" to search engine and you should be good to go.

    Great Alternative

    Got these with TSW Nurburing wheels, everything works and they look great too. Got these because it has the steel key so it is a lot stronger.

    whish they were a little bigger

    they look really nice, and getting a replace for the key seems pretty easy (not that is easy to lose the key..) in case that something ever happens it also gives you clearance when using the torque wrench so you don't have to use extension to not scrap your paint and works with 19mm socket or the factory socket

    Nice little lug nut

    These are nice Lug nuts I took one star away only because they do sit inside of the rim (10th ann. Cobra wheel) where they are not noticable. Standing next to the wheel mounted the lugs are not visible unless peering into the holes. Next time I will pay a bit more for longer lugs that will be more visibly appealing and safer cause they can be seen on a walkaround.

    Better off in the trash!

    These go on easy enough and look good when on the car. But good luck trying to get these things off the lug without shearing off the spline. I was pulling off these nuts and only two came off all the way and those were twisted and you can see where it was about to break the others snapped off at the end of the spline. Save yourself the trouble and DO NOT buy these!!!

    A perfect fit, and doesn't take away from wheels.

    I recently installed 20” Sporza V5 Stain Black staggered wheels on my 2010 GT. I am glad I purchased these black six spine lugs nuts with key because the stock Ford lugs nuts were not going to fit and would have taken away from the beauty of these wheels. I highly recommend these nuts if you’ve got a wheel that’s all black and tight tolerances to avoid scuffing your wheels. The key works out perfectly giving you the extra space away while removing and torquing your wheels.
