Explanation:
The width of a hexagonal nut across flat surfaces is directly proportional to the nominal diameter of the bolt. The empirical formula for calculating the width of the hexagonal nut across flat surfaces is as follows:

Width of hexagonal nut across flat surfaces = 1.5 × D

Where D is the nominal diameter of the bolt.

Therefore, option C is the correct answer.

Key Points:
- Width of hexagonal nut across flat surfaces is proportional to the nominal diameter of the bolt.
- Empirical formula: Width of hexagonal nut across flat surfaces = 1.5 × D
- Option C is the correct answer.
