Thread Rolling Screws Thread rolling screws are a type of threaded fastener that forms threads that securely and reliably fasten into materials through pre existing holes Thread rolling screws form threads in material by pushing material outward Because of this the most popular application for thread rolling screws are when you must avoid Thread Forming Screw Thread forming screws are assembled into a plain pilot hole forming their own internal thread by cold swaging This eliminates the need for thread tapping provides a significant assembly cost reduction The strength of a swages thread is greater than a cut thread because the grain flow of the steel is maintained hi life tools thread rolling dies Radiused Runout With the controlled radiused root runout offered by Hi Life the smooth radius continues up to the point where the thread blends in the shank or to the head of the screw this radius distributes stresses evenly increasing442 Visit us on the WEB EBNinc com Evansville IN 812 477 0077 Jasper IN 812 482 5105 Vincennes IN 812 882 4090 Henderson KY 270 830 0077 Owensboro KY 270 684 0877 Mt Vernon IL 618 244 7156 Thread Cutting and Rolling Machine Screw HoleCut Thread vs Rolled Thread Many product designers or engineers don t go to this level of detail when sending specs for their fastener or threaded part Instead the decision is left to the machine shop to make the recommendation if the shops on the RFQ list
