Claim:
A structural member including an arm connection comprising: a first thru-vang having a plurality of apertures disposed therein, the first thru-vang secured to the structural member; a second thru-vang adjacent the first thru-vang and having a plurality of apertures therein, the second thru-vang secured to the structural member; an arm bracket having a plurality of bracket apertures disposed therein and adjacent to the first thru-vang and the second thru-vang such that the bracket apertures align with the apertures of the first thru-vang and the second thru-vang; a plurality of pins mutually received through the apertures in the first and second thru-vangs and the bracket apertures, the plurality of pins containing a securement aperture on one end; wherein at least one of the pins has a flattened head at an end opposite the securement aperture, with the flattened head being flattened parallel to the length of the pin; and wherein the plurality of pins have a tapered end which provides for the pins to be axially aligned through the apertures in the first thru-vang and the second thru vang and the bracket apertures more easily than if the pins had a uniform diameter along their entire length.
