What is thread rolling?
thread rolling by RA White
 

Thread Rolling is a process where threads are formed by moving material instead of cutting away material. Dies which are much harder than the material to be rolled have a mirror image of the thread form ground into them. The part is rotated and pushed into the die. The pressure causes the material to flow into the die, forming the thread. Cold working of the material during thread rolling makes the threads stronger and more fatigue resistant than cut threads. Rolling is a fast process and is the most cost effective way to produce threads.
