Explore our certified range of high-tensile, low-temperature, and special alloy fasteners engineered for heavy-duty industrial configurations.
A comprehensive technical brief on structural calculations, metallurgy, and applications in extreme environments.
In structural engineering, the selection of fastening elements directly determines the integrity of steel frames, heavy machinery, marine hulls, and critical aerospace architectures. Among these, Custom Self-Drilling and Self-Tapping Screws have evolved from simple light-gauge sheet metal fasteners into highly engineered, application-specific structural components. Understanding the underlying mechanical principles and metallurgical profiles is key to optimizing assembly efficiency and preventing critical structural failures.
Self-drilling screws feature a point modeled after a drill bit, allowing them to drill their own pilot hole, tap the internal thread, and secure the joint in a single operation. Self-tapping screws, on the other hand, require a pre-drilled pilot hole, utilizing their hard, sharp threads to cut or form corresponding mating threads in the substrate material.
High-performance fasteners rely heavily on chemical composition. Utilizing super stainless steels, titanium alloys, nickel-base superalloys (such as Inconel 718), and carbon-manganese structural steels guarantees structural survival across extreme temperature variations ranging from cryogenic environments (-270℃) up to high-temperature combustion chambers (1200℃).
By eliminating independent drilling, punching, and tapping processes, self-drilling fastener systems reduce field labor by up to 50%. This directly lowers the Total Cost of Ownership (TCO) in mega-scale energy projects, petrochemical refineries, and marine construction sites where thousands of units must be installed daily.
Established in 2015 in the global manufacturing and logistical hub of Shanghai, China, Beiersdorf Industrial Technology (Shanghai) Co., Ltd. has grown to become an engineering leader in the design, testing, and production of custom-engineered special fasteners and ultra-high precision components.
“Product quality is the foundation for an enterprise's survival.”
“Heart to sunshine, everything to prosperity”
Our mission is to provide global industries with fasteners that refuse to fail under dynamic load, salt spray exposure, high shear pressures, and thermal shock. We align our manufacturing processes directly with ASTM, DIN, ISO, and China Classification Society guidelines to deliver reliable products.
Our facility in Shanghai is equipped with multi-station cold heading machines, precision CNC grinders, high-temperature furnace lines, and an integrated testing center.
Why Tier-1 global engineering firms choose Beiersdorf as their preferred technical vendor.
Quality control is not an afterthought; it is our foundation. We have formulated the most stringent sampling inspection system, utilizing automated optical sorting, ultrasonic defect tracking, and hardness mapping to strive to achieve zero defects for all products leaving our Shanghai production line.
Supported by a specialized team of metallurgists and tooling engineers, we continuous innovate our fastener geometry. At present, our group holds more than 100 utility model patented products and eight core invention patented products, driving advanced thread-forming concepts.
To support global Just-In-Time (JIT) programs, we maintain an optimized supply chain. We currently operate nearly 100,000 product models, with 500 tons of specialized high-alloy raw materials in stock, and 10,000 tons of finished stainless steel standard parts ready for containerized shipping.

How our fasteners are deployed to solve critical engineering challenges in major global industries.
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 Duplex, L7, 40CrNiMoA, Inconel 718, EN14399 steel structure connection pairs, and certified marine fasteners backed by major classification societies.
Our thermal and high-tensile fasteners are widely applied in power transmission pylons, turbine assembly rigs, nuclear container sealing systems, and solar arrays. High mechanical performance is critical for handling continuous wind loading, seismic stress, and thermal expansion cycles.
By using alloys with low creep values, our power grid and generation clients prevent unexpected joint relaxation and maintain stable clamping force over decades of active service.
Railway and high-speed rail transit networks subject mechanical connections to constant dynamic vibrations. Under these conditions, standard fasteners can fail due to vibration fatigue. We manufacture precision self-tapping structural assemblies that maintain high shear and tensile strength under dynamic stresses.
From locomotive engines and bogie parts to trackside control enclosures and line electrifications, we deliver high-reliability fastening products.
With the expansion of 5G antennas, server architectures, and cleanroom semiconductor equipment, there is growing demand for micro-sized precision components and non-magnetic materials. Our non-magnetic series and high-precision machined screws prevent magnetic interference, safeguarding sensitive transmission signals.
Additionally, we supply lightweight plastic fasteners made of PEEK and PVDF to support cleanroom installations and electronics assembly processes.
Corrosion resistance is the primary requirement in refinery piping, desalination installations, and deep-well exploration equipment. High exposure to acids, hydrogen sulfide, and chlorides makes carbon steel fasteners unusable. We address this with fasteners in Inconel, Monel, and Super Duplex Stainless Steel (2205/2507).
These materials offer excellent resistance to pitting and stress corrosion cracking in aggressive chemical processing environments.
How manufacturing concentration, raw material integration, and logistics planning work together to benefit global buyers.
Our manufacturing center in Shanghai has direct access to the Yangtze River Delta's high-grade metal processing hub. This provides a steady supply of high-end raw materials like Inconel, cobalt-based alloys, and super duplex steel. This density keeps material sourcing cycles short and keeps costs competitive.
Unlike standard off-the-shelf fastener distributors, our plant specializes in custom-made orders. Whether you need custom self-drilling screw lengths, specific thread types, custom drill point geometries, or high-tensile strengths up to 1900 MPa, our engineers handle everything from drawing to pilot production.
Located near the Port of Shanghai, the world's busiest container port, we offer fast transit times, competitive shipping rates, and efficient customs clearance. Our warehouse is organized to support quick deliveries, reducing inventory holding costs for our global customers.
Answers to key technical questions from procurement officers, QA/QC inspectors, and structural design engineers.
The differences lie in their point geometry and installation steps:
Hydrogen embrittlement is a serious concern for high-tensile components. We prevent this through strict controls, including careful raw material sourcing, low-hydrogen chemical processing, heat treatment cycles, and systematic baking processes after electroplating to release trapped atomic hydrogen. We also run mechanical load tests on every batch to confirm safety before shipment.
For marine environments, we recommend high-alloy options. These include A4-80 (316 Grade) or A5-80 stainless steels, Duplex 2205, Super Duplex 2507, and nickel-base superalloys (such as Inconel 718 or Monel 400). These materials offer excellent resistance to pitting and stress corrosion cracking from exposure to seawater and salt spray.
We provide full documentation, including EN 10204 3.1 Mill Test Certificates, material composition analysis, dimension inspections, hardness testing reports, and certification from major classification societies for marine projects (such as CCS).
For non-standard custom alloys (like Inconel 718 or Titanium alloys), MOQs depend on the size of the fastener and the available raw material stock. If the raw material is in stock, we can often supply small pilot batches for engineering testing. Please contact our sales team with your technical drawings for a specific quote.
