Abstract
A threaded bolt may be produced according to a method including the steps of: forming a cylindrical bolt blank of metal with a root end and a head end, and with a section of the bolt blank adjoining the root end that is reduced in diameter up to a region designed for the formation of lead-in flights. Then, in a first rolling phase, partially form the principal thread flights and the lead-in thread flights using a first pass of flat jaws of a thread rolling machine. Then, in a second rolling phase, fully form the principal flights and the lead-in flights and forming grooves.
