Abstract
A ribbed tapered swage pin includes a head structure at a distal end which has a decreasing taper in the direction of the distal end and one or more ribs or lands positioned around the outer perimeter which, when helically driven, gradually plastically deform the swage boss of one part to form a swage joint with the hole of another part. A swaging tool with which such a swage pin may be used would, therefore, include a rotary actuator and a screw feed for driving the swage pin with a helical rotation and thrust to move through and thereby cold work the swage boss to form the swage joint.
