Abstract: A method of installing a threaded fastener from one side of a hole through a substrate. The fastener includes a collar and a bolt having a head, a threaded tail portion and a tool engagement portion extending from the tail. The method includes: (a) engaging the tool engagement portion with a bolt engagement portion of a tool (b) passing the bolt through to the far side of the hole and supporting it there by way of the tool, (c) passing the collar through the hole while supporting it with the tool; (d) assembling the bolt and collar to form the threaded fastener having a head larger than the hole; (e) engaging a nut to tighten the fastener; and (f) detaching the tool from the fastener. Separation of the bolt engagement portion and the tool engagement portion is prevented by a moveable member, which engages both portions.
