Wedge based fastener

A fastener, comprising:

• a shaft extending along a longitudinal axis, the longitudinal axis passing through a cross-sectional centroid of the shaft;
• and
• a sleeve wrapped partially around the shaft, the sleeve comprising an inner surface adjacent the shaft, an outer surface, an upper extent, a lower extent, a first circumferential extent, a second circumferential extent, and a gap extending longitudinally from the upper extent to the lower extent and separating the first circumferential extent from the second circumferential extent,
• the sleeve having a first thickness adjacent the first circumferential extent and a second thickness between the second circumferential extent and the first circumferential extent, the first thickness being less than the second thickness;
• wherein the sleeve has a first rotational position relative to the shaft and a second rotational position relative to the shaft different from the first rotational position,
• wherein the longitudinal axis is in substantially the same location in both the first and second rotational positions, and
• wherein the sleeve has an angle between the inside surface and the outside surface of about 8 degrees or less, the angle being defined between a tangent to the inside surface and a tangent to the outside surface.
