Threading
After the head is formed, threads are added either by rolling or cutting. High-quality socket screws use thread rolling, where the blank is pressed between dies to deform the material into the thread shape
. Rolled threads are stronger than cut threads due to work-hardening and uninterrupted grain structure around the threads
. (Cut threading is used in some cases, but rolled threads are preferred for superior fatigue strength.)


Increased Load Distribution:
To achieve the required hardness and tensile strength, screws are then heat treated. For alloy steel parts, this typically involves quenching (rapidly cooling from a high temperature) to harden, followed by tempering at a moderate temperature to toughen and relieve brittleness. This process yields the high strength grades (e.g. property class 10.9 or 12.9) expected of socket cap screws
