Explore our primary industrial fastening components direct from Handan Yongnian's manufacturing lines.
Handan Yongnian District Dongshuo Fastener Manufacturing Co., Ltd. was established in 2015. Located in the core region of China's structural metalware production clusters, we have evolved into a highly integrated enterprise specializing in the design, engineering, and manufacturing of state-of-the-art fastener products. Our core goal is to deliver unparalleled structural integrity to commercial projects, bridging the gap between heavy metal production capacities and strict global engineering standards.
With an advanced fabrication site, high-precision multi-stage cold-heading equipment, and standardized thread-rolling machinery, we operate under rigorous quality control standards. This infrastructure supports a diverse catalog of high-strength fasteners, custom-engineered steel nails, anchor configurations, washers, and specialized bolts tailored to demanding architectural specifications.
"We are committed to providing high-quality fastener products and providing customers with comprehensive solutions in various industries."
Our material capabilities span mild carbon steels (such as SAE 1008, 1018, and 1022), medium-alloy carbon steels, and stainless steels (SUS 304, SUS 316). Every batch of raw wire rod undergoes strict chemical composition verification before moving to the drawing and heading processes. By controlling metallurgy, we ensure that our steel nails, drywall screws, and industrial bolts meet required tensile strengths and shear values.
Furthermore, our in-house testing equipment allows us to analyze microstructure stability, surface integrity, and structural failure limits under high load environments. This rigorous process is why industrial clients choose us for high-grade fastener requirements.
How we address wear resistance, stress corrosion cracking, and hydrogen embrittlement through surface coatings.
Our zinc oxide electroplating and hot-dip galvanizing technologies create an engineered barrier. This prevents oxygen and moisture from attacking the carbon steel core. This process exceeds 72-hour to 500-hour salt-spray tests as specified by international requirements.
High-carbon steel fasteners undergo thermal stress-relieving cycles directly after acid pickling. This step drives out monatomic hydrogen, preventing delayed fracture and hydrogen-induced cracking in heavy-duty applications.
Our dry wall nails feature black and grey chemical conversion phosphate coatings. This porous crystalline structure creates an ideal base for dry construction compounds and joint compounds, maximizing adhesion and prevent pull-out failure.
To support high-speed robotic assembly systems globally, we run optical sorting sorting systems. High-resolution CCD cameras capture structural parameters of screws, nuts, and washers on a high-speed conveyor. Fasteners with thread deformation, head burrs, or dimensional deviations are automatically rejected, keeping defect rates below 50 PPM (Parts Per Million).
By using automated sorting, we ensure consistent performance in high-speed automatic nail guns and screw feeders. This reduces assembly failures and downtime on site.
How our fastener products meet specific structural requirements in global markets.
High-speed bugle-head phosphate drywall nails engineered to quickly penetrate light-gauge steel framing without pre-drilling.
Hexagon socket cap bolts DIN 912 and flange bolts DIN 6921 engineered for heavy machinery, automotive frames, and industrial pipelines.
Hexagonal self-drilling screws with EPDM washers designed to handle seasonal rainfall and high wind load demands.
High-tensile Grade 8.8 and 10.9 structural bolts and assemblies built to withstand vibrations and dynamic shear loads.
In modern industrial applications, fasteners are critical load-bearing components. Selecting the proper steel grade and surface finish prevents structural failures. For example, in humid coastal environments, standard carbon steel without surface treatment can degrade rapidly. This rust expansion can damage surrounding masonry and concrete structures.
By manufacturing specialized washers (such as DIN 125, spring washers, and custom flat plates), we distribute clamping pressure evenly. This design protects the joint surface and maintains torque levels, even under thermal cycling and mechanical vibration.
Why global B2B procurement managers trust Handan Dongshuo for high-volume fastener programs.
Our pricing model adapts to purchase volume and packaging specifications. Operating in a major steel producing cluster allows us to offer stable pricing even during raw material market fluctuations.

Technical and logistics answers for procurement engineers and global buyers.
A1. We are a direct manufacturing factory located in Handan, Hebei Province, China. Our facilities handle cold heading, thread forming, polishing, and quality testing. Customers are welcome to visit our plant.
A2. Our plant is located in Handan City, Hebei Province, China. The nearest airport is Handan Airport, located approximately a one-hour drive from our facility. We can arrange ground transportation for visiting clients.
A3. No, we do not maintain a static price list. Fastener prices fluctuate based on raw steel costs (carbon steel, stainless steel, brass), energy prices, and plating requirements. Please send your specifications directly to us for a custom quote.
A4. For orders under USD 1,000, we require 100% payment in advance. For orders over USD 1,000, terms are 30% T/T deposit in advance, with the balance due before shipment. We accept multiple global currencies, including USD, EUR, and RMB (Renminbi).
A5. Yes, we provide free samples for standard configurations from stock. The buyer is responsible for international courier shipping costs. For custom OEM sizes, tooling and setup fees apply.
A6. Yes, we build to standard specifications, including DIN (e.g. DIN 912, DIN 6921, DIN 125, DIN 603), ASTM, ISO, and JIS. Every shipment is accompanied by a material test report verifying dimensions and grade compliance.
A7. For standard catalog items, production is completed within 20 to 30 days of deposit confirmation. Custom OEM parts requiring new tooling generally require an additional 10 to 15 days for tooling design and validation.
A8. Yes, we support custom packaging. We can customize bulk outer cartons, retail inner boxes, polybags, and structural wooden crates with your company logo and barcode labeling.
A9. We package bulk products in heavy-duty polybags within corrugated boxes, secured on fumigated wooden pallets and shrink-wrapped. This prevents moisture ingress and thread damage during sea transit.
A10. Every batch is traceable back to its production run. If a quality issue is found, our team will analyze the retention samples and test records. We will issue a corrective action plan and replace any non-compliant products.
