Spline drive lug nuts. Aluminum do not last and do not shave enough weight to make any deference.
They are made for spline drive lug nuts. I was in the wheel industry for over 11 years.don’t know the exact measurement but the hole is no lie barely bigger than the lugs in the pic i posted i assume they had to make it like that cause it’s one of those wheels that have 10 lug holes 5 for 5x100 and 5 for 5x114.3. also thanks for the suggestion
