High-strength, non-magnetic, corrosion-resistant, and special material fasteners customized for critical industrial applications.
In modern industrial assembly, the demand for flush surfaces combined with high shear strength and structural stability has led to the extensive deployment of Countersunk Bolts and Nuts. Unlike traditional protruding hexagonal or socket head caps, countersunk designs distribute clamping force over a broader conical surface. This minimizes localized stress concentrations and eliminates aerodynamic or physical drag, which is vital in aerospace aerodynamics, maritime hull linings, high-speed rail, and precision machinery.
Choosing the correct countersunk component requires a deep understanding of standard angles—typically 90 degrees in metric ISO/DIN specifications and 82 or 100 degrees in unified national coarse/fine (UNC/UNF) imperial configurations. Achieving an optimal flush fit requires meticulous alignment of the countersunk angle of the bolt with the pre-chamfered hole of the mating material. A mismatch of even a few degrees can cause single-point stress loading, leading to accelerated fatigue failures under dynamic loading cycle conditions.
Established in 2015 and strategically headquartered in Shanghai, China, Beiersdorf Industrial Technology (Shanghai) Co., Ltd. has established itself as an innovative force in manufacturing and exporting high-performance fasteners and ultra-high precision components.
"Product quality is the foundation for an enterprise's survival."
"Heart to sunshine, everything to prosperity."
We work with global engineering firms to supply advanced fasteners. Our inventory includes special grade stainless steel, titanium, and nickel-based superalloys designed for complex engineering challenges. We operate a modern factory to serve demanding global sectors, offering reliable custom parts alongside standard configurations.
How Beiersdorf ensures performance integrity and supply chain efficiency across all fastener categories.
We have formulated the most stringent sampling inspection system, so as to strive to achieve zero defects for the products out of our factory. Every batch undergoes rigorous quality checks for dimensional accuracy, tensile properties, and material composition.
At present, our entire group has more than 100 utility model patented products and eight invention patented products. Our engineering team continually researches metal fatigue and corrosion resistances for challenging application environments.
We currently operate nearly 100,000 product models, with 500 tons of special raw materials in stock and 10,000 tons of finished stainless steel standard parts in stock. This ensures quick turnaround times and stable bulk supply chains.
Understanding the performance limits of advanced structural materials in high-stress and harsh industrial applications.
Traditional structural steel quickly reaches its limits when exposed to acidic environments, extreme sub-zero ocean currents, or jet exhaust pathways. Beiersdorf bridges this gap by developing specialized metallurgical compositions for demanding engineering situations.
Engineered for cryogenic systems, LNG tanker hulls, and space launch assemblies. These retain structural ductility, preventing brittle failure under low-temperature conditions.
Constructed using superalloys (such as Inconel and Cobalt alloys) that resist oxidation, creep deformation, and thermal expansion fatigue at operational temperatures up to 1200℃.
Known for high strength-to-weight ratio and excellent resistance to chloride corrosion. Widely utilized in performance-critical aerospace and marine engineering applications.
Specially heat-treated alloy fasteners that provide high structural clamping forces, suitable for critical connections in heavy industrial machinery and rail systems.
From deep-sea marine engineering to localized wind farms, here is how our fasteners perform in actual projects.
In ship hulls, offshore platforms, and subsea pipelines, countersunk fasteners reduce drag and prevent marine growth adhesion. Beiersdorf supplies CCS (China Classification Society) certified bolts using Super Stainless Steel (Duplex 2205) and A4-80 grades, ensuring resistance to galvanic corrosion and seawater erosion.
Fasteners used in structural bogies and undercarriages must withstand continuous vibrations and mechanical shocks. Our 1900 MPa high-strength countersunk bolts maintain clamp preloads over millions of cycles, reducing maintenance requirements and enhancing passenger safety.
In aerospace components and cleanroom precision equipment, avoiding magnetic interference is critical. Beiersdorf custom non-magnetic titanium and engineering plastic countersunk fasteners provide secure holding power without impacting sensitive electronic sensors.
Our special fasteners are widely used in the field of shipbuilding and oceanography engineering, specifically in the manufacture of special ships, marine propulsion, marine accessories, yacht manufacturing, offshore oil drilling platforms, submarine pipelines, offshore wind power, underwater lifeboats, port machinery, dock construction, etc.
These special fasteners mainly include A4-80, A5-80, D8-80, D6-70, 2205, L7, 40CrNiMoA, 718, EN14399 steel structure connection pair, classification society certificate fasteners, etc.
Engineering roadmap focusing on smart manufacturing, additive processes, and weight reduction.
Moving from high-tensile carbon steels to corrosion-resistant titanium, cobalt, and nickel-based superalloys. This change is designed to meet requirements for aerospace and extreme-temperature applications.
Adopting advanced cold-heading techniques, CNC machining, and automated optical sorting. These processes help us meet precise tolerances and support a near-zero defect rate (Hash Detection).
Integrating digital material tracking from raw metal melt batches to finished products, providing verified mechanical property documentation for critical engineering applications.
Industrial supply chains depend on resilience, material availability, and production flexibility. Operating from Shanghai, Beiersdorf utilizes an established local industrial network that integrates raw material sourcing, mold fabrication, heat treatment, and logistics. This setup allows us to keep raw material costs stable and maintain short lead times even during market shifts.
Our stocking strategy helps manage market volatility. With a permanent inventory of 500 tons of specialized raw materials and 10,000 tons of finished stainless steel parts, we can quickly scale production from custom prototyping runs to large-volume global shipments. This reliability helps our international partners keep project schedules on time.
