    High-strength bolt sizes for 8.8, 10.9 and 12.9 grades are usually selected by load, joint design, thread engagement, and installation method. The grade tells you the strength level. The size tells you whether the bolt has enough cross-sectional area for the actual job. A larger bolt is not always the best answer.
