A blind fastener (10) employs a split bolt element (12) having two symmetrical half sections (14a,14b) split at mating separation faces (44) and cooperatively displaceable between a first collapsed position and a second expanded position. A capture portion (20) split bolt has a substantially circular plan form in the first collapsed position with a diameter which is received through an attachment hole (38) in a structural member (34). A bearing section (24) and a threaded portion (26) both have a substantially circular plan form in the second expanded position while the capture portion has compression surfaces extending with an elliptical major axis greater than the hole diameter in the extended second position to engage a bottom surface surrounding the attachment hole. The bearing section closely engages the attachment hole in the expanded position. A wedge separator element (30) is insertable between the half sections to expand them from the first collapsed position to the second expanded position. A nut (32) is threadably received on the threaded portion and engages a lip on a mounting aperture in a monument to be attached to the supporting structure.
