Default Grade 8 front fender bolts

Harley used grade 8 bolts on the front fender of the 2006 Dyna. Is there a reason for the grade 8 bolts?

Curious.

Harleys vibrate. That can make bolts shear. Even grade 8s. I added Kuryakyn adjustable passenger foot pegs to my ‘03 Ultra. The extra weight increased vibration and the grade 8 bolt sheared off and my whole floorboard fell off. I bought Rivco adjustable passenger floorboards. They come with a base that stabilizes the bolt, its been on my bikes for ten years. In ‘07 they upgraded to two bolts holding the passenger floorboards on.
