ABSTRACT:
A structural joint for a space frame having connecting members or nodes and tubular structural member is provided in which the shank of a connecting bolt, whose head is located within the hollow end portion of the tube, extends through an aperture in the tube end for engagement with a threaded opening in the node. The tube shank has a longitudinally extending keyway formed therein in which a key is slidably received. A nut or sleeve having an unthreaded inner bore receives the bolt shank and has an internal keyway which receives a portion of the key to rotatably lock the nut and bolt together so that the nut may be rotated to rotate the bolt and engage its shank in the threaded opening of the connecting member.
