Torque to specs (actually use a torque wrench). **Q: Will they fit on s 2008 honda accord?** A: The lug nuts will fit the car, but you need to make sure an acorn style lug nut will fit the wheel you are putting on **Q: What is the overall diameter of the nut** A: Regular diameter of any lug nut. However I don't recommend them because the inner cavity the key goes into, stretches and rounds out within 1-2 times of torquing them.
