What caused Seattle crane to collapse?
Wait... isn't that exactly what londons_explore says is wrong, and essentially the source of confusion in the first place?

I think it's right. He seemed to be describing hollow pins with threaded holes. The pins hold the sections together, the bolts screw into, and steady the pins.

Correct. What I said only applies to this particular use of bolts to hold pins in place, which in turn hold the truss together.
