A fastener that includes a shaft and a sleeve is provided. The shaft
extends along a longitudinal axis that passes through a central portion,
e.g., the centroid of a head of the shaft. The sleeve is wrapped
partially around the shaft. The sleeve has a gap that separates first and
second circumferential extents thereof, 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 is less than the second thickness. The sleeve has a first
rotational position relative to the shaft and a second rotational
position relative to the shaft different form the first rotational
position. The longitudinal axis is in substantially the same location in
both the first and second rotational positions.
