Thread Rolling Guide: Cold-Formed Threads, Strength & Process

Thread Rolling Guide: Cold-Formed Threads, Strength & Process

Short answer: Thread rolling cold-forms threads by pressing a hardened die into a rotating or fed blank so the material flows plastically into the thread profile, keeping the grain continuous along the root for higher fatigue strength and no swarf. It is the standard method for bolts, screws, studs and fasteners in steel and stainless, delivering faster cycle times and a better surface than cutting or grinding threads.
