Abstract: The present disclosure provides a method for manufacturing a work piece, such as fasteners or flange nuts. The method produces a work piece with a thickened wall. This can be accomplished using a plurality of successive stamping dies to reduce the diameter of a cup-shaped feature drawn from a blank, and reforming the cup-shaped feature to a formed shape having a thickened wall. A fastener or flange nut with a thickened wall manufactured by stamping and forming is also disclosed.

Abstract: A self-locking push-on clip fastener for securing two components together is disclosed. The clip fastener includes a u-shaped clip body that includes upper and lower legs and a curved end that connects the legs. The clip body has an open end into which the component to be attached is inserted. The legs are movable between an initial, spaced apart arrangement in which the component may be inserted into the clip body, to a final component-engaging position in which the component is captured between the legs. A slidably movable u-shaped trigger is attached to the clip body. A trigger-guiding channel is formed on the inner wall of one or both of the legs of the clip body. The trigger is slidably movable in the channel. An interlock system comprising first and second windows is formed in one of the legs of the clip body and a flange extending from the trigger.
