I hate quoting the internet. I don't trust any of it unless it agrees with me. Here is a quote from good old Wikipedia.

"Threads of metal fasteners are usually created on a thread rolling machine. They may also be cut with a lathe, tap or die. Rolled threads are stronger than cut threads, with increases of 10% to 20% in tensile strength and possibly more in fatigue resistance and wear resistance."


Right is right, even if everyone is against it, and wrong is wrong, even if everyone is for it. - William Penn
