I believe the metal sleeves that the bolts go into are the pins.

Edit: I probably shouldn't have said "sleeves". That has more than one meaning in this context. I'm talking about hollow pins, secured by bolts when I say "sleeves".




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.
