In the modern industrial landscape, "Security" in fasteners refers to two critical dimensions: the integrity of the joint and the prevention of unauthorized access. Global enterprises in the 5G infrastructure, renewable energy, and public transportation sectors are increasingly demanding high-security screws to protect high-value assets from vandalism and environmental fatigue.
Procurement teams are shifting from "Just-in-Time" to "Just-in-Case" strategies. China's top secure screw factories, such as Handan Yongnian Dongshuo, offer the massive production scale required to buffer against global logistics volatility, ensuring that critical infrastructure projects stay on schedule.

Our fastening solutions are engineered for extreme environments, providing the bedrock for global industrial progress.
High-torque hexagonal self-drilling screws and galvanized dry wall nails optimized for earthquake-resistant building codes and rapid modular construction.
Specialized flange bolts and nylon lock nuts designed to withstand the unique vibration frequencies of electric vehicle powertrains and battery housings.
Corrosion-resistant U-Bolts and threaded rods for solar panel mounting systems, capable of enduring 25+ years of exposure to harsh UV and coastal salt spray.
Established in 2015, Handan Yongnian District Dongshuo Fastener Manufacturing Co., Ltd. is a premier enterprise specializing in the production and operation of high-performance fasteners. Our company is committed to providing high-quality fastener products and comprehensive solutions across various industries.
As a reputable manufacturer, we leverage advanced production equipment and a professional technical team to meet the most rigorous international standards (DIN, ISO, ASTM). Our facility in Handan, China, serves as a global hub for secure screw innovation.
We are pioneering the use of Zinc-Nickel alloy coatings that provide over 2000 hours of salt spray resistance, significantly outperforming traditional galvanization. This is crucial for offshore wind and marine engineering.
Looking toward the "Industry 4.0" future, our R&D is exploring integrated load-sensing technology within bolts to monitor structural health in real-time for bridges and skyscrapers.
Beyond the standard cross-recess, we offer proprietary head designs (Pentagon, Snake-eye, Torx-Plus with Pin) to ensure that only authorized personnel with specific tools can service the equipment.
Our roadmap includes a 100% closed-loop water system and solar-powered cold-heading machines to meet the growing demand for green-certified supply chains.
Navigating international trade requires more than just a good product; it requires legal and technical harmony.
Full compliance with RoHS, REACH, and CE standards. We provide material mill certificates and heat treatment records for every batch shipped.
Strategically located in Handan with direct access to Tianjin Port, ensuring competitive sea freight rates and optimized transit times for bulk orders.
Our engineers provide local language CAD drawings and torque calculation support to ensure the right secure screw is specified for your specific load requirements.
The price is negotiable. It can be changed according to your quantity or packaging. We offer direct factory pricing without middlemen.
All of our products are made of high-quality environmentally friendly materials, ensuring long-term durability and safety.
You can send your own design and logo. We can open new molds and logos, providing rapid prototyping for custom secure screw needs.
We provide free samples for standard items so you can verify the fit and finish before committing to a large-scale purchase.
A1. We are a direct factory located in Handan City, Hebei Province. We welcome all clients to visit our facility to inspect our production lines and quality control processes.
A2. We implement a multi-stage inspection process, including raw material chemical analysis, dimensional checks during cold-heading, and final hardness/tensile strength testing after heat treatment.
A3. Yes. Our facility is equipped for high-volume manufacturing. For orders over 1000 USD, we typically work on a 30% T/T advance basis with the balance due before shipment, ensuring a secure transaction for both parties.
A4. After technical parameter confirmation and mold development, initial samples are usually ready in 7-14 days. Bulk production varies by quantity but typically ranges from 21-35 days.
A5. Absolutely. Whether you need DIN (German), ANSI (American), or JIS (Japanese) standards, our technical team can adjust manufacturing tolerances and thread pitches to meet local requirements.
