We offer a comprehensive range of screw production equipment—including cold heading, thread rolling, and assembly machines—alongside full-specification drilling tail screws, supported by ODM, OEM, and non-standard customization services.
As an indispensable core supporting device in the full fastener production line, this industrial thread rolling machine is professionally optimized for mass thread rolling processing of standard screws, self-tapping screws, industrial bolts and special-shaped fasteners. It effectively solves common defects of traditional threading processes, including broken metal fibers, insufficient thread structural strength, surface burrs, uneven tooth shapes and low production efficiency.
As a fully automated and high-efficiency Automatic Screw Thread Rolling Machine, it has become the standard precision processing equipment for modern high-quality fastener manufacturing factories worldwide.
The core working principle of the YWC automatic screw thread rolling machine is metal cold extrusion plastic forming technology. After completing the pre cold heading process, cylindrical screw blanks are automatically and stably fed into the precision rolling station. The equipment is equipped with two sets of high-hardness alloy thread rolling dies that operate in synchronous opposite rotation.
With stable and constant mechanical extrusion pressure, the dies uniformly compress the outer circle of screw blanks, guiding the metal material to flow regularly along the preset thread profile, so as to form standard, full-toothed, smooth and high-precision thread teeth, realizing standardized molding for all kinds of fastener threads.
This professional chipless thread forming equipment completely avoids damage to the original metal fiber structure of screw blanks caused by traditional cutting processes. On the contrary, cold rolling extrusion compacts and strengthens the metal texture on the thread surface, significantly improving the thread's tensile strength, surface hardness, wear resistance and fatigue resistance.
The entire thread rolling process adopts pure physical cold forming with zero metal scrap loss and zero thread tooth damage, which is the core advantage that makes the YWC high precision thread rolling machine far superior to conventional thread cutting equipment.

Different from traditional lathe cutting and tooth picking processes that peel off metal layers and destroy fiber integrity, the YWC automatic screw thread rolling machine adopts integrated cold extrusion forming technology. It completely retains the complete metal fiber streamline of screw blanks, making the thread tooth structure denser, more solid and structurally stable.
The processed thread surface features no tool marks, no burrs and no tooth collapse, achieving high-standard smooth finish and precise dimensional tolerance. As a professional fastener thread making machine, it thoroughly upgrades the outdated traditional thread processing mode and improves overall fastener quality.
Fastener threads processed by this industrial thread rolling machine achieve comprehensive upgrades in structural performance and service life. After precise cold extrusion rolling, the thread surface forms a uniform and dense hardened layer, which greatly enhances the screw's tensile resistance, shear resistance and anti-loosening stability.
Compared with traditional cut threads, the strength of roll-formed threads is increased by more than 20%, fully meeting the high-load, high-precision and long-service-life application requirements of mechanical equipment, automotive engineering, 3C electronics and precision hardware industries.
This high-performance full automatic screw threading machine integrates automatic vibration sorting feeding, precise positioning, synchronous high-speed rolling and intelligent automatic discharging into one streamlined workflow. The entire production process requires no manual intervention, realizing true unmanned continuous operation.
Equipped with YWC exclusive intelligent PLC control system, it supports one-key startup, automatic specification adaptation, real-time fault alarm and overload safety protection. It effectively solves the pain points of low output efficiency, unstable precision and high labor dependence of semi-automatic thread processing equipment, realizing standardized and intelligent mass production for fastener threads.
Adopting pure metal plastic deformation processing principle, this chipless thread forming equipment achieves zero metal scrap and zero material waste throughout the whole thread rolling process, with material utilization rate reaching up to 100%. It effectively saves high-cost raw materials such as stainless steel and high-grade carbon steel for fastener manufacturers.
Meanwhile, the matched high-hardness rolling dies feature ultra-long service life and low replacement frequency, greatly reducing daily consumable costs and equipment maintenance pressure, cutting down the comprehensive production cost of thread processing for factories.
The YWC automatic screw thread rolling machine boasts excellent multi-specification and multi-scene universal compatibility. By replacing matched standard rolling dies and simply adjusting system parameters, the equipment can quickly switch production of metric, imperial and special customized standard threads.
It stably processes M2-M20 various specifications of screws, bolts and self-tapping fasteners covering iron, carbon steel, alloy steel and stainless steel materials. One automatic bolt thread roller meets diversified order production demands, realizing multi-functional flexible production and improving factory operational flexibility.
The YWC screw thread rolling machine is essential core post-processing equipment in the complete fastener cold heading production line. It is widely applicable to standardized precision thread processing for construction hardware, furniture fasteners, 3C electronic micro screws, automotive anti-rust fasteners, mechanical equipment bolts and industrial precision fasteners.
It perfectly adapts to mass production of high-strength and high-precision fasteners, being the preferred industrial thread rolling machine for global fastener enterprises to upgrade production automation and product quality standards.
