Thread Rolling Versus Thread Cutting
A rolled thread is stronger than a cut one because the process changes its physical properties by cold forging. The procedure supplants the part’s malleable material with hardened steel die formed to thread size and form.
Unlike the weakening effect of cutting threads that remove material, thread rolling moves molecules into the thread form, making it dense to improve quality and strength. Burnishing the steel dies produces a superior micro-finish that reduces wear and extends the life of your fastener.
