Explore our core manufacturing line of industrial fasteners, custom engineered for structural safety and thermal integrity.
In the domain of advanced mechanical design, micro-fastening technology plays a crucial role. Small self-tapping screws are not merely scaled-down versions of standard fasteners; they are specialized components designed to manage mechanical loads, friction coefficients, and structural variations in thin-walled materials. As industries like consumer electronics, medical implants, automotive sensors, and aerospace telemetry move toward miniaturization, the demand for precision-engineered screws has increased significantly.
A successful small self-tapping screw implementation requires balancing the material's properties with the thread design. Choosing between thread-forming designs (which mold the mating material without generating debris) and thread-cutting profiles (which carve matching threads in harder or more brittle materials) affects the longevity, strip-out resistance, and vibration resistance of the joint.
We maintain a rigorous quality assurance program and supply system to ensure our micro-fasteners perform reliably under extreme conditions.
We have established a rigorous sampling inspection system designed to identify and eliminate variations, targeting zero-defect manufacturing for every production lot.
Our group holds more than 100 utility model patented products and eight invention patents, showing our continuous investment in fastener design and performance.
We manage nearly 100,000 product models, maintaining 500 tons of special raw materials and 10,000 tons of finished stainless steel standard parts in stock for prompt dispatch.

1200℃ High-Temperature Fastener
Specially processed alloys designed to maintain clamp load and resist thread relaxation under elevated temperatures, such as in combustion chambers and exhaust lines.
As modern devices become more compact, fastener sizes are scaling down. Thread profiles such as M1.0, M0.8, and even smaller require high precision. At this scale, traditional thread profiles are often insufficient because thread friction dynamics change significantly. We employ 3D profile modeling to refine thread flank angles, which helps prevent thread stripping and reduces installation torque requirements. This profile engineering minimizes micro-cracking in sensitive polycarbonate housings and ultra-thin metal plates.
Standard carbon steel often lacks the durability needed for high-performance applications. Our material selection process covers specialized alloys, including titanium grade 5 (Ti-6Al-4V) for medical equipment and nickel alloys for chemical processing plants. Our coatings, such as micro-zinc-flake and electro-less nickel passivation, provide consistent friction control and galvanic corrosion protection. These coatings allow our screws to perform reliably in contact with carbon fiber reinforced polymers (CFRP) and aluminum panels without inducing galvanic degradation.
In automated, high-speed assembly, driver slip can damage sensitive components. We address this by utilizing modern driver interfaces like Torx Plus® and custom spline geometries. These designs increase the torque transfer surface area, reduce driver wear, and prevent cam-out. This design allows automated systems to apply precise tightening force, ensuring reliable assembly across production runs.
Our structured production lines cover major special material categories utilized across precision industries.
Precision fastening issues can affect operations across multiple industries. If a micro screw fails on a satellite circuit, in a surgical tool, or on an offshore oil sensor, it can lead to operational disruptions and high repair costs. High-performance micro fasteners must be selected based on the specific requirements of the application:
Subsea structures and offshore marine equipment operate in demanding environments. Standard steel fasteners can suffer from localized pitting and crevice corrosion. We address these requirements with super duplex steel and classification-society-certified alloys. These materials resist chloride-induced stress corrosion cracking and maintain joint integrity in submerged equipment, subsea pipelines, and marine propulsion systems.
Transitioning to hydrogen and cryogenic fuels presents unique storage challenges. Under cryogenic temperatures down to -270℃, standard metals can become brittle and fracture. Our specialized cryogenic fasteners are manufactured from select nickel-chromium and titanium alloys that preserve their mechanical properties, ductility, and tension profiles at extremely low temperatures, helping protect cryogenic storage units and distribution pipes from leakage.
5G transceivers and high-frequency antenna arrays require assemblies with minimal electromagnetic interference. Ferrous screws can distort magnetic fields, causing signal loss. To address this, we supply non-magnetic fasteners made from specialized high-purity polymers and non-magnetic titanium grades. These materials secure circuit boards while preventing signal distortion.
Our engineering capabilities cover a range of demanding 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, L7, 40CrNiMoA, 718, EN14399 steel structure connection pair, classification society certificate fasteners, etc.

To manage quality in micro-screws, manual inspection is replaced by automation. Beiersdorf uses high-speed automated optical sorting machines equipped with high-resolution cameras to verify every screw. Thread pitch, shank diameter, drive depth, and point geometry are measured while in motion. Parts with anomalies down to the micron level are separated, helping maintain consistent quality and minimize production line issues.
Global supply chains require full transparency. We track our raw materials from the initial melt to the final fastener. Our materials are accompanied by EN 10204 3.1 chemical and physical test certificates. This documentation helps aerospace, medical, and automotive clients confirm compliance with regulatory frameworks like RoHS, REACH, and custom PPAP protocols.
Sourcing custom materials often involves long lead times. To support stable operations, Beiersdorf maintains 500 tons of specialized raw materials—including nickel super-alloys, duplex steel, and titanium rods—along with over 10,000 tons of finished standard stainless steel parts. This inventory management strategy helps absorb supply chain disruptions, stabilizing lead times and product availability.
Frequently asked engineering and logistics questions regarding precision fasteners.
For high-corrosion applications, we recommend A4-80 (316) stainless steel, titanium alloys (such as Ti-6Al-4V), or nickel super-alloys (Inconel 718) depending on the environment. Titanium offers low weight and excellent corrosion resistance in chloride environments, while nickel alloys perform well under elevated temperatures and chemical exposure.
Thread-forming screws displace material to form mating threads without generating debris, making them suitable for ductile plastics like ABS and polycarbonate. Thread-cutting screws have cutting edges that remove material as they are driven, which helps reduce radial stress in harder, more brittle plastics like thermosets or glass-filled nylons.
We combine advanced tooling with automated optical sorting systems. Every production run undergoes automated visual inspection, measuring dimensional variables, pitch profiles, and drive geometries. This system helps isolate out-of-tolerance parts before packaging.
Yes. We provide Classification Society certified fasteners for marine and shipbuilding projects. We also offer material test reports in accordance with EN 10204 3.1, confirming chemical composition and mechanical properties for compliance audits.
