Thread rolling other methods
There are four methods used to produce screw threads. The technique chosen for any one application is selected based on constraints; time, money, the degree of precision required, availability of equipment, what equipment based upon the volumes to be produced.
Generally, specific thread-generating processes fall along a line from turned toolroom-made screws to mass-produced parts; thread rolling is the dominant method, all other methods historically based.
Cut threads are weaker than Rolled threads, rolled threads can have an up to 20% in tensile strength and increase fatigue and wear resistance.
