Abstract
The invention includes a method, and a component made according to the method having at least one thread pattern formed thereon from a stamping method. The invention includes a tubular member comprising a body having a wall formed from a wrapped sheet of stock to define an interior wall and an exterior wall, a seam in the wall defining a first and second end of the wrapped sheet of stock, and a thread pattern stamped on the exterior wall. The method comprises the steps of forming a blank from sheet of stock having a first surface. A thread pattern is formed onto the first surface while in a substantially sheet-like form. A bending operation then forms the sheet stock into a tubular member such that the thread pattern, located on the tube's external surface, is substantially aligned about its circumference.
