A disc-drive assembly including an actuator arm, a load beam and a swage mount. The actuator arm has a thickness (T.sub.A), an arm tip with a width (W.sub.A), and arm-hole with a diameter (D.sub.A) in the actuator arm. The load beam has a load beam hole. The swage mount has a flange with a width (W.sub.F). The swage mount has a hub with an outer hub diameter (D.sub.OD), extending from the one side of the flange. The outer hub diameter (D.sub.OD) of the hub is less than 2.54 mm. The flange width (W.sub.F) divided by the hub outer diameter is greater than 2.0. The ratio of the outer hub diameter (D.sub.OD) to the actuator arm thickness (T.sub.A) is less than 1.5, and the ratio of the diameter of the arm hole (D.sub.A) to the width of the arm tip (W.sub.A) is less than 0.5.
