Claim:
1. A blind fastener comprising: a collet body including a first end defining a generally circular opening and a first wall portion adjacent to the first end, where the first wall portion includes an interior surface, an exterior surface, a protrusion extending from the exterior surface including a leading face oriented towards the first end and a trailing face oriented away from the first end, wherein the first wall portion defines at least two secondary slots extending longitudinally from the first end to respective terminus to form at least two flexible fingers, each having a distal end at the first end, a second end defining a generally circular opening and a second wall portion adjacent to the second end, where the second wall portion has an interior surface and an exterior surface, wherein one of the interior surface of the first wall portion, the second wall portion or the first wall portion and second wall portion includes a threaded portion, and wherein the second wall portion comprises a first part of a two part anti-rotation means; and a cylinder body comprising a first end defining a generally circular opening and a first wall portion adjacent to the first end, where the first wall portion has an interior surface and an exterior surface, and a second end defining a generally circular opening and a second wall portion adjacent to the second end where the second wall portion includes a tool interface for receiving a rotation arresting tool during operation of the fastener, wherein the cylinder body comprises a second part of a two part anti-rotation means, and wherein the first and second parts of the two part anti-rotation means are matable to permit axial translation there between but prevent substantial rotation there between; and wherein the collet body second wall portion defines an external diameter, wherein the cylinder body first wall portion defines an external diameter and wherein the collet body second wall portion diameter is substantially the same as the cylinder body first wall portion diameter.
