For the same reason, rolled threads are often much smoother, and damage resistant during handling than cut threads. Thread rolling changes the mechanical properties of the material by work hardening it, resulting in increased wear and fatigue resistance, as well as enhanced shear, tensile, and yield......

Thread rolling is a metal forging process that forms screw threads by passing material under high pressure through a set of hardened dies. In the thread rolling machine, dies are skewed or pitched relative to one another, so their axes are not parallel.

The materials most commonly used to make thread-rolling dies are high-speed tool steels, high-chromium tool steel, medium-alloy cold-work steel. Which are mostly Ferrous but other ductile materials such as brass, aluminium are also used with compromise in quality of the thread.

Thread rolling is a mechanical process where threads are cold formed when the part is squeezed between two thread dies on a thread rolling machine. Thread rolling provides for a stronger thread and no loss of material.

Thread rolling is a cold working process where a machined blank is compressed between rotating or reciprocating dies, whose thread profile is ground into the dies. As the blank cylinder is penetrated by the dies, the metal flows into the die cavities and forms the thread profile into the part.

Threads produced using a thread rolling machine are 30% stronger than untreated cut threads of the same size, however heat treatment and post-processing of cut threads will reduce this difference. Thread rolling machines use a smaller diameter blank than a screw-cutting machine.
