See our high-speed cold heading machinery, multi-station bolt formers, automated thread rolling systems, and strict QC testing laboratories in action. Discover how we process raw carbon steel, stainless steel, and alloy materials into precision-threaded male-female standoffs and complex custom fasteners.
Our facility maintains strict thermal treatment control, physical tensile testing, and automated chemical plating, ensuring all structural components stand up to the most demanding international installation parameters.
Male-Female screws, also known widely as threaded standoffs, spacer bolts, or gender-changing fasteners, play a crucial role in modern electromechanical assemblies, structural steel connections, and integrated solar racking systems. Unlike conventional standard bolts, these specialized fasteners feature an external male thread on one end and an internal female thread on the other. This unique design allows engineers to achieve precise, rigid spacing between components while maintaining electrical grounding or structural alignment.
The manufacturing process has evolved from slow manual lathe operations to high-throughput, multi-station cold heading and high-speed CNC thread-rolling. This transition has dramatically reduced unit costs while improving thread accuracy (typically conforming to Class 6g/6H tolerances). Handan Ningyuan Fastener utilizes advanced cold forming tools to preserve raw steel grain structures, resulting in higher fatigue resistance and tensile load capability compared to cut-threaded alternatives.
Available in premium high-grade brass, marine stainless steel (SUS304/SUS316), lightweight nylon, and zinc-plated carbon steel to meet various application requirements.
CNC machining and strict tool tracking achieve thread concentricity down to ±0.02mm, preventing thread binding and structural loosening under vibration.
Offers custom surface finishes, including hot-dip galvanizing, electro-galvanizing, zinc-nickel alloy plating, and black oxide coating to withstand harsh industrial environments.
Industrial procurement managers looking for "China Male Female Screws Factory & Companies" look beyond unit cost. Key metrics include structural reliability, consistent manufacturing tolerances, and compliance with environmental regulations. Sourcing from Yongnian (Handan)—the global capital of industrial fasteners—offers significant supply chain benefits:
| Material Type | Tensile Strength (MPa) | Corrosion Resistance | Primary Industrial Use Cases |
|---|---|---|---|
| Carbon Steel (Zinc Plated / HDG) | 400 - 800 (Grade dependent) | Moderate to Excellent (HDG) | Solar brackets, HVAC support systems, building pipe galleries |
| Stainless Steel (SUS 304/316) | 500 - 700 | Outstanding | Chemical processing plants, marine installations, outdoor telecom |
| Brass (Alloy 360) | 330 - 450 | Good | Electrical switchboards, circuit board mounting, RF shielding |
| High-Quality Nylon (PA66) | 60 - 80 | Chemically Inert | PCB insulation, electrical components, lightweight automotive assemblies |
Beyond electronic standoffs, Handan Ningyuan's engineering division designs heavy-duty structural steel components. In large infrastructure projects, male-female studs connect C-shaped and U-shaped steel profiles to form rigid framework grids.
In photovoltaic utility plants, outdoor fasteners must withstand wind loads, snow, and thermal cycling for over 25 years. Ningyuan’s hot-dip galvanized C-beams, brackets, and heavy-duty connectors use proprietary anti-corrosion coatings to resist red rust in coastal and humid environments. Similarly, our building electromechanical seismic systems isolate lateral mechanical forces during seismic events, protecting critical utility pipe galleries and HVAC ducts.
As global engineering demands evolve toward lightweight and high-strength fasteners, Ningyuan is continually upgrading our production processes:
Ningyuan operates a modern 20,000-square-meter facility equipped with more than 50 advanced cold heading machines, thread rollers, and multi-axis CNC machining centers. This layout supports efficient high-volume production while maintaining tight dimensional tolerances.
Our in-house quality control laboratory runs hardness testers, optical sorting systems, salt spray testing equipment, and torque testing rigs. This ensures every production batch—from standard wedge anchors to custom male-female threaded spacers—meets international quality standards.

Ningyuan operates under rigorous quality management systems to meet strict automotive, construction, and mechanical quality requirements.
Our heavy-duty steel and galvanized components are engineered to build durable support networks for utility, telecom, and solar infrastructure.
We supply complete C-shaped, U-shaped, and H-rail mounting profiles, designed for fast installation and excellent corrosion resistance in utility-scale solar farms.
Engineered seismic hangers and expansion anchors to secure building utility structures against seismic events, meeting local construction safety standards.
Strong steel clamps designed to mount to structural beams without drilling or welding, maintaining the integrity of the load-bearing framework.
High-tensile concrete anchors that provide high pull-out resistance, securing heavy structural components directly to concrete foundations.
Detailed technical answers addressing core procurement questions and structural engineering requirements for male-female screws.
Male-female screws are used to mount and space components in electromechanical, industrial, and construction setups. In electronics, they mount PCBs, separate components to prevent electrical shorts, and assist with thermal management. In heavier industrial systems, they are used to build rigid frameworks with steel brackets, and mount sensors, utility boxes, and electrical panels.
For outdoor solar and utility environments, carbon steel with a hot-dip galvanized (HDG) coating is preferred for its strength and cost-efficiency. For coastal or highly corrosive industrial sites, stainless steel (SUS304 or SUS316) is recommended to prevent galvanic corrosion and preserve structural integrity over a 25+ year lifespan.
Yes. Our in-house R&D and tooling departments design and produce custom fasteners based on customer drawings or technical specifications. This includes custom thread profiles, non-standard lengths, special hex head dimensions, and specific surface plating options.
Our manufacturing processes are ISO9001 certified. We supply fasteners that comply with RoHS, EU REACH, GB/T30512 automotive standards, and ELV 2000/53/EC regulations. Our laboratory conducts regular mechanical tests, including tensile, yield, hardness, and salt-spray testing.
Lead times depend on the complexity of the part and order volume. Standard catalog products with existing tooling usually ship within 10 to 15 days. Custom parts requiring dedicated tool design and custom plating typically require 25 to 35 days, including testing and quality assurance checks.
