I own a SawStop cabinet saw. I used a dado blade for the first time in my life...... My understanding is that I can use as much as 13/16" width. I dropped in a width of 5/8", added the Arbor washer then the Arbor nut. I was surprised that the bolt section of the Arbor did not stick out the other side of the Arbor nut. Made me nervous. Is this normal? Did I miss something?

Worked like a charm, but still made me nervous.
