Abstract
A disk drive head stack assembly includes an actuator arm tip that includes a swaging hole centered about a swaging axis. A first suspension assembly has a first swage boss that protrudes into the swaging hole. A second suspension assembly has a second swage boss that protrudes into the swaging hole and does not contact the first swage boss. Each of the first and second swage bosses includes an inner lip that extends radially closer to the swaging axis than any other part of that swage boss. The inner lip thickness of the first swage boss, measured parallel to the swaging axis, increases more greatly with increasing radial distance from the swaging axis than does the inner lip thickness of the second swage boss.
