Bike help, cracked a "hub bolt" ... pictures..

[Adam G]

Yeah, I need this part "identified". I don't know what it would be called. I'm hoping that they sell them separately from the hubs, otherwise I need to purchase a new hub and re-spoke the entire thing, then re-align the wheel, again...

Let's just say this happened in a crash. It was kind of cool!
Anyway...
