Abstract

See full text

A method of reducing the cycle time required for flow-drill screw operations by providing a dimple on a part that is engaged by a flow-drill screw. A tip of the flow-drill screw engages a contact band at a location spaced from the tip of the distal end of the flow-drill screw and base portion of the dimple. Friction between the flow-drill screw tip and dimple creates a heat concentration area and results in displaced material fanning a threaded collar. The flow-drill screw is secured by the threads of the threaded collar.
