Hello Tim Dukes

Bolt preload can be applied using the preload tool as shown in image below. 

Although let me check back with the team on more clarity on the statement as seen in your first image. 

While defining the bolt, the SAE standard bolt heads are predicted automatically based on the size in the geometry and defined accordingly. 
Let me check with the team if a custom size can be defined here.
