Explore our foundational industrial fasteners engineered for structural resilience, PV mount stability, and seismic resistance.
In high-precision electronics, industrial hardware machinery, telecommunications, and building electromechanical systems, the demand for precision component separation is critical. Stand off screws (commonly referred to as threaded standoffs or spacer bolts) serve a vital structural purpose: dual-ended spacing and grounding, ensuring reliable mechanical clearance between PCBs, chassis, brackets, and panels.
As global industries demand tighter tolerances and superior corrosion resistance, choosing the correct manufacturer becomes crucial. Standard standoffs from low-end workshops fail to meet industrial requirements, resulting in stripped threads, galvanic corrosion, and component short-circuiting. At Handan Ningyuan Fastener, we solve these integration issues by combining high-end CNC machining, automated thread rolling, and premium surface treatments to ensure our fasteners withstand structural loads and environmental stresses.
Whether you require brass standoffs for consumer electronics, stainless steel standoffs for marine-grade equipment, or custom threaded pillars for industrial photovoltaic arrays, our engineering team manufactures parts that conform to stringent international standards, including ISO 9001, RoHS, REACH, and GB/T automotive compliance.
Founded in 2005 (formerly known as Jin Langtao), Handan Ningyuan Fastener Manufacturing Co., Ltd. is located in Handan Yongnian, widely recognized as the fastener capital of China. For over 18 years, we have transitioned from a localized manufacturing workshop into a modern, integrated enterprise specializing in the R&D, production, and global supply of high-end fasteners.
We operate in a state-of-the-art facility covering 20,000 square meters, staffed by 66 dedicated employees, including 6 senior design engineers and 15 highly skilled technicians. Armed with over 50 advanced cold-heading, thread-rolling, and precision CNC turning machines, we generate an annual sales revenue of 70 million yuan.
Our comprehensive service scope spans high-end standardized fasteners and bespoke engineering solutions, including building electromechanical seismic hanger components, pipe gallery support systems, steel structure anchor bolts, self-drilling screws, and photovoltaic new energy mountings.
How the Yongnian industrial cluster enables our production capacity, quality assurance, and pricing competitiveness.
Yongnian is situated near Hebei's steel-producing hubs. This proximity guarantees a steady supply of high-grade carbon steel, stainless steel, and alloy round bars, insulating our production schedules from raw material shocks.
The concentration of heat-treatment providers, surface plating shops, tooling makers, and logistics firms in Handan reduces material transport times. This efficiency allows us to complete custom standoff orders quickly.
Leveraging high-end testing labs and modern quality management systems, our products undergo inspection using profile projectors, thread-go-no-go gauges, hardness testers, and salt spray testing equipment.

A comprehensive engineering review to help you choose the right stand off screw for your application.
When specifying threaded standoffs, selecting the appropriate material and thread format dictates the mechanical resilience and operational lifespan of the assembly. The table below highlights the standard materials we process:
| Material Type | Common Grades | Mechanical Advantages | Target Applications |
|---|---|---|---|
| Brass | C3604, HPb59-1 | Excellent conductivity, non-magnetic, easy to machine. | PCB mounting, high-frequency telecommunications. |
| Stainless Steel | SUS303, SUS304, SUS316 | Extreme tensile strength, superior corrosion resistance. | Medical devices, marine components, chemical plants. |
| Carbon Steel | 12L14, 1215, Mid-Carbon | High cost-efficiency, heat-treatable for hard mechanical wear. | Heavy industrial frames, structural support systems. |
| Nylon / Polymer | PA66 (Polyamide 66) | 100% electrical insulation, lightweight, corrosion-free. | High-voltage switchgear, sensitive electronics. |
How we address environmental compliance, customized logistics, and technical documentation requirements.
We supply complete compliance paperwork including RoHS (Restriction of Hazardous Substances), REACH (SVHC declaration), and ELV (End-of-Life Vehicles) directives. This documentation ensures seamless customs clearance and safety conformance.
Whether you require standard hexagonal standoffs or bespoke turned parts with knurled steps, our engineers can translate your PDF designs, 3D CAD models (STEP/IGES), or physics samples into production-ready blueprints.
Through partnerships with international freight forwarders, we arrange EXW, FOB, CIF, DDU, and DDP shipments. This coordination ensures predictable transit times and custom-clearance procedures directly to your assembly line.
Threaded standoffs are evolving alongside modern technology. Here is how they are applied in emerging sectors.
The expansion of electric vehicle (EV) battery packs and charging stations requires lightweight, insulated spacing systems. Multi-material hybrid standoffs (combining brass inserts with injection-molded glass-fiber nylon jackets) provide mechanical mounting and reliable galvanic isolation between cell modules.
Ningyuan's expertise in manufacturing C-shaped steel, seismic brackets, and hot-dip galvanized fasteners guides our heavy-duty standoff design. In utility-scale solar arrays, large-diameter standoffs support electrical combiner boxes, resisting heavy winds, thermal expansion, and seismic tremors.
5G outdoor antennas and base stations operate under harsh weather conditions. To prevent signal interference and degradation, manufacturers utilize stainless steel (SUS316) and aluminum-alloy standoffs with passivated coatings. These options offer weatherproofing and electrical grounding without introducing RF noise.
