Experienced Thread & Fillet Rolling

Our thread and fillet rolling services provide high strength, precision formed components for demanding engineering applications. As a specialist forming process, rolling enhances the mechanical properties of components without removing material, making it ideal for high performance and fatigue-critical parts.

Thread rolling is a cold forming process where hardened dies apply pressure to a component, displacing material to create accurate thread profiles. Unlike traditional cutting methods, this process strengthens the material by maintaining and refining the grain structure, resulting in improved durability and surface finish.

Fillet rolling is a complementary process used to strengthen critical transition areas—such as underhead radii on fasteners—by applying controlled pressure to reduce stress concentrations and improve fatigue life
