Abstract: A thread profile is first rolled into a cylindrical work piece with a first set of thread dies, wherein the metal free-flows into the grooves of the first set of dies to form a rounded (or other shape) crest. Then the thread is re-rolled in a second set of dies having a reduced groove depth such that the rounded crest is re-formed and flattened. A thread profile may also be formed in a cylindrical work piece using a set of dies having surfaces containing two or more distinct groove shapes. Diagonally cut grooves encountered by the work piece would have a shape substantially identical to a “normal” die groove profile with a depth of D+H. Grooves in contact with the work piece as it exits the die would have a shape with a reduced groove depth of approximately “D.

Abstract: A fastener having an aligning lead thread that does not follow the helical pattern of the fill threads around the shank of the fastener. The aligning lead thread is located on the shank distant from the first full thread to enable the engage the threads of a receiving member to pull the fastener elements into alignment rather than a standard lead thread which becomes trapped behind the threads of a receiving member.
