This vehicle has both new standard based on ISO* and previous standard bolts/nuts. There are some differences between these two types of bolts/nuts: shape of the head, grade of strength, hexagonal width across flats and the standard tightening torque.

- For guidance in discriminating, refer to Tightening Torque Table (New Standard Included).
- The new standard machine screws and tapping screws have a head of ISO standard torx recess.
- If the tightening torque is not described in the description or figure, refer to Tightening Torque Table (New Standard Included).
