Threading rolling machines
Thread rolling machines handle workpieces from 3 to 16 mm in diameter with output rates up to 300 parts per minute. They are used for chipless cold forming of external threads on bolts, screws, studs, and fasteners—enhancing strength and fatigue resistance without material removal.

Thread rolling machines shape threads through plastic deformation rather than cutting, preserving the grain structure of the material. This results in superior tensile strength, fatigue life, and surface finish compared to machined threads. Modern YUHAI R-series models (R3-20Z, R4-40Z, R8-130Z, R16-200Z, etc.) feature CNC control, automatic feeding, and real-time pressure monitoring for consistent quality.
These machines are essential in automotive, construction, energy, and appliance manufacturing, where high-volume production of reliable fasteners is critical. Quick-change rolling dies allow rapid switching between metric, inch, trapezoidal, and custom thread profiles.
KNAVI GROUP supplies thread rolling machines directly from YUHAI (China). All units undergo pre-shipment testing, come with full English documentation, and include up to 2 years of warranty. Tooling kits for DIN, ISO, or custom specifications are available upon request.
Direct factory supply ensures fast delivery worldwide. Operator training and on-site commissioning are included.
