Flyin' Miata aluminum lug nut (set of 20)

Made of 7075-T6 aluminum alloy for high strength, fully threaded and light weight (~1 oz each), these are some high performance lug nuts. They use a 19mm socket for the best combination of strength and clearance. We even put the torque spec right on the side of the nut just in case you have a senior moment. Not that this would ever happen to you.

You can use an impact on these, although the anodizing will wear off - to avoid that, break them loose by hand, then use an impact to spin them off. 

The knurled style allows you to spin the nut on and off quickly but requires a deep socket.

Fits all Miatas as well as other cars with a 12x1.5 thread pitch.
