Pin-connected

Pin-connected is a type of construction where many of the truss members (especially the high-load members) are connected together by a pin, or bolt, that passes through holes in each of the members. This pin is typically threaded on both ends, smooth in the middle, and a lomas nut is used to tighten the members together.
