*Solved Crank shaft bolt not threading in...... ***Repost from my build for visibility

So interesting problem today. I picked up some hardware for the crank and the crank bolt won't fit.
When I try to thread it in it just won't take and gets jammed. This is by hand though. I don't want
to add any torque to it until I consult with you guys. The threads on the bolt seem to be nice and
uniform. The crank threads I can't get a good read on but obviously there is a problem. I'm thinking
I need to chase the threads in the crank shaft. Or do I put a little elbow grease into it with a socket
and ratchet?
