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.
