A pin connector means for removably affixing structural members to central nodes enabling the erection of structural latticeworks is disclosed. The pin connector means includes a ball-ended bolt, a bearing seat, and a means for coupling a spherical ball of the ball-ended bolt to the bearing seat. The surface of the spherical ball and the contact surface of the bearing seat are finished to be of low friction. A threaded rod extending from the spherical ball of the ball-end bolt screwably affixes into an endpiece of a structural member. The bearing seat for receiving the spherical ball of the ball-ended bolt is affixed to a central node. Each of the central nodes can receive a plurality of the pin connector means. The latticework comprises a plurality of central nodes and a plurality of structural members, the structural members being enabled to removably affix to the central nodes using a pin connector means.
