AI Auto-Generated Blueprint Visualization
Real-time algorithmic optimization for non-standard geometries and load-bearing capacities.
Targeting Complex Demands: Custom Sizes & Special Materials
Designed specifically for buyers, engineers, and procurement managers who require precise custom sizes, unique thread profiles, and extreme-environment materials that off-the-shelf products simply cannot provide.
Aerospace & 5G Materials
We process a vast array of special materials required by high-tech industries. From high-tensile Titanium alloys and Inconel for aerospace applications to highly conductive Copper and specialized Stainless Steel (304, 316, 410) for 5G communications and energy storage systems. All materials comply strictly with REACH and ROHS environmental standards.
Extreme Custom Sizing
Our engineering support team excels in translating your specific requirements into reality. Whether you need micro-screws starting from M1 for consumer electronics or robust M16 bolts for automotive parts, our multi-station cold heading and CNC capabilities ensure perfect dimensions with tolerances as tight as 0.006mm.
Comprehensive OEM Services
We are experts in non-standard fastener solutions, providing one-stop hardware assembly solutions. Our OEM services cover everything from automated screw production, gasket stamping, and nut manufacturing to highly complex precision customized lathe parts. We adapt to your supply chain needs flawlessly.
Advanced Manufacturing & Engineering Support
Our expansive facilities house specialized workshops for every stage of production: automatic screw production, gaskets, lathes, nuts, and stamping.
Extensive Mold Library
Thousands of existing molds reduce custom sampling time by up to 60%.
State-of-the-Art Equipment
We invest heavily in cutting-edge machinery to guarantee versatility and speed. Our production floor boasts multi-station cold heading machines (two-mode four, three-mode three, three-mode six, four-point cold heading), tooth rolling machines, and combined tooth rolling machines capable of producing M1-M16 screws.
For stamping and turning, our high-precision stamping machines feature progressive dies capable of producing parts over 0.1mm thick, and single dies for 3-5mm thicknesses. Our machining centers and CNC lathes produce precision customized lathe parts, while centering machines handle complex cylindrical components. Automatic lathes efficiently produce knurled and inlay nuts from M2 to M16.
AI-Enhanced Quality Control & Laboratory
On the basis of high-quality production technology, we enforce strict quality control measures. We guarantee zero defects through our optical separation workshop, full inspection workshop, and fully equipped laboratory.
Optical Sorting Technology
Our optical sorters utilize AI-driven image recognition to accurately detect screw dimensions and microscopic defects. This prevents mixing and allows us to inspect more than 600 screws per minute. To ensure 100% flawless appearance, our full inspection workshop conducts rigorous visual inspections, guaranteeing product uniformity.
Mechanical & Stress Testing
- Hardness: Vickers and Rockwell hardness testers ensure exact material strength.
- Torque: Torque meters detect and record values to meet strict customer torque requirements.
- Tensile Strength: Tensile machines test the ultimate breaking point of materials.
- Hydrogen Embrittlement: Specialized refrigerators test dehydrogenation to prevent catastrophic product breakage.
Chemical & Environmental Analysis
- X-ray Fluorescence Spectrometer: Conducts elemental analysis and verifies environmental protection compliance (ROHS/REACH).
- Corrosion Resistance: Salt spray testing machines simulate harsh environments.
- Precision Measurement: 2D measuring, digital display micrometers, ring gauges, needle depth meters, and metallographic cutting/inlay machines ensure absolute dimensional fidelity.
Certified with ISO9001, ISO14001, and IATF16949, we proudly hold the title of "High-Tech Enterprise". We have established long-term cooperation with global giants such as Xiaomi, Huawei, KUS, and SONY. Our products are integral to 5G communications, aerospace, electric power, new energy, AI, automotive parts, and healthcare industries globally.
The Customization & Sampling Process
We provide comprehensive pre-sale, in-sale, and after-sales service, including R&D and personalized customization. Here is how we bring your concept to life:
Engineering Consultation
Submit your CAD drawings or technical requirements. Our R&D team analyzes the application, load requirements, and environmental factors to recommend the optimal material and manufacturing method.
Mold Matching & Creation
We first consult our extensive mold library. If a match is found, sampling time is drastically reduced. If a completely non-standard profile is needed, our in-house tooling department creates custom progressive or single dies rapidly.
Prototyping & Lab Testing
Initial samples are produced and subjected to our rigorous laboratory tests—including torque, tensile, salt spray, and optical sorting—ensuring the prototype meets or exceeds your precise specifications before mass production.
Frequently Asked Questions
Common inquiries about our non-standard fastener solutions and OEM services.
What types of non-standard fasteners can you customize?
We specialize in customizing a wide range of non-standard hardware, including micro screws (M1), large bolts (up to M16), specialized nuts (knurled, inlay), custom gaskets, elastic/flat/square pads, precision stamping parts, and complex CNC lathe components with tolerances down to 0.006mm.
