1/2"-20 Lug Nuts, Spline Type, Open End

When switching to aftermarket wheels, you will most likely need to get small diameter lug nuts.  The bore holes in those wheels are much smaller than the OEM. 

When even the smallest hex type lug nut wont work, a spine type usually will.  These lug nuts offer the smallest available overall diameter that will work with pretty much any wheel out there. These also have the added benefit of offering some security for your wheels compared to a standard hex lug nut. You should measure the bore holes on your wheels before ordering and compare them to the dimensions provided. 

Unlike the hex type lug nuts found HERE, these are sold as a set with the appropriate spline key.
