Abstract
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.
