12mm x 1.5. I got lugs with my wheels from Vitek at Kozz Tuning. They are a closed end type. I don't know the make. I have taken the fronts off 5+ times already and no stripping. I'm sure he could hook you up with whatever you want for a good price. Make sure a new tuner style lug will work with a stock Toyota wheel, if that's what your asking also. I know my lugs from my other wheels wouldn't work with the stock Toyota wheels because Toyota wouldn't put the stock ones back on with out that type of lug and washer..
