摘要： 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 one of the interior and exterior wall. The method comprises the steps of forming a blank from sheet of stock having first and second opposing surfaces and at least a first and second edge. A thread pattern is formed onto at least one of the first and second opposing surfaces extending between the first and second edge while in a substantially sheet-like form. Following the formation of the thread pattern, the method includes bending the sheet stock into a tubular member such that the thread pattern on one of the first and second surfaces is substantially aligned about a circumference.
