Defining Excellence in Hardware Manufacturing
When searching for a reliable Screw and Bolt manufacturer, consistency, precision, and capacity are paramount. Yuhuang has established a complete process of automated and intelligent production system, achieving full-chain autonomous production from raw material processing to product formation. We don't just supply fasteners; we engineer long-term reliability for your assembly lines.
Our Core Fastening Solutions
Our cutting-edge manufacturing facilities allow us to produce an extensive catalog of standard and non-standard customized fasteners. From micro-electronics to heavy machinery, our product range covers all your engineering needs.
Machine Screw & Bolt
Our precision Machine Screw and standard Bolt selections are manufactured with uniform threads to ensure superior tensile strength. Designed to be used with a tapped hole or a nut, these components are essential for heavy-duty machinery, automotive assemblies, and structural engineering.
Self Tapping Screws
Engineered for efficiency, our Tapping Screws and Self Tapping Screws feature specialized thread geometries that cut their own mating threads into materials like plastic, wood, and metal. This eliminates the need for pre-drilling, significantly accelerating your assembly process.
Security Screws
Protect your intellectual property and prevent vandalism with our robust Security Screws. Featuring unique, tamper-resistant drive designs (such as pin-in-torx or snake-eye), these fasteners are critical for public infrastructure, sensitive electronics, and medical devices.
Captive & Sems Screw
Streamline your inventory management and ensure safety compliance. A Captive Screw remains attached to the panel, preventing loss during maintenance. Meanwhile, our Sems Screw units come with pre-assembled free-spinning washers, drastically reducing assembly time and part tracking overhead.
Sealing Screw
For applications exposed to harsh environments, liquid, or gas, our Sealing Screw technology integrates a resilient O-ring directly under the screw head. This provides a 360-degree hermetic seal, ensuring IP-rated waterproof and dustproof performance for aerospace, marine, and outdoor electronics.
Five Professional Production Workshops
The company is equipped with industry-leading production equipment, featuring high precision, high efficiency, and large-scale production capabilities. We effortlessly meet the dual demands of standard parts mass production and complex non-standard customized orders.
Screw Production
Equipped with multi-station cold heading machines, three-mold six-half machines, and combined thread rolling machines. We stably produce M1-M22 full-range screws, covering tiny precision electronics to large-sized fastening bolts.
Lathe Workshop
Relying on centering machines, advanced machining centers, and CNC lathes, we specialize in cylindrical and customized lathe parts. We achieve an industry-leading ultra-high precision level with minimum tolerances reaching 2-3 threads (0.02-0.03mm).
Stamping Workshop
Outfitted with high-precision continuous dies and single-station machines. We produce ultra-thin precision stamping parts below 1.0mm, and high-strength stamping parts up to 3-5mm thick, ensuring precise dimensions and stable formation.
Nut & Gasket Workshops
Capable of processing M2-M16 standard nuts, knurled nuts, and embedded nuts. Our gasket division handles mass batch production of spring washers, flat washers, and various sealing components with mature processes.
Lean Management Concept
Choosing a long-term supplier means partnering with a facility that prioritizes quality control at every micro-step. Our production process strictly follows the lean management concept. From raw material cutting, forging, and thread rolling, to stamping, lathe finishing, and surface treatment, each process is under standardized, intelligent control.
This achieves the perfect combination of automation and refinement. Whether you require millions of standard Machine Screw units or a small batch of highly complex, non-standard customized Captive Screw assemblies, Yuhuang can respond quickly and produce efficiently. We guarantee stable delivery, unified quality, and provide customers with a seamless, one-stop hardware component manufacturing service.
