Products Introduction
Our tantalum hexagon socket screws are produced by cold forging and precision turning processes and go through 12 quality control links from raw materials to finished products to ensure the consistency and reliability of each product. The raw material is high-purity tantalum ingots melted by vacuum arc, and the grain structure is refined through forging to improve the fatigue resistance of the product; subsequently, CNC precision turning is used to process the thread and head, and with the precise molding of the inner hexagonal groove, the gap-free bite between the tool and the screw is realized to avoid the risk of sliding teeth during installation.
In terms of surface treatment, we provide two options: passivation treatment and polishing treatment. Passivation treatment can form a dense tantalum oxide film on the surface of the screw, further improving the corrosion resistance, and is suitable for extreme environments such as the chemical industry and the ocean. Polishing can obtain a smooth surface with Ra ≤ 0.8 μm, reduce medium residue, and meet the hygienic requirements of medical, food processing, and other industries. The product specifications cover M2-M12, with a length range of 5-100mm. Non-standard sizes can also be customized according to customer needs, including fine-tooth threads, full/semi-tooth structures, and special head shapes.
Each piece of tantalum hexagon socket screw has undergone strict testing before leaving the factory: the purity of the material is verified by the spectral analyzer, the accuracy is detected by the thread pass and stop gauge, and the corrosion resistance is verified by the salt spray test and corrosion immersion test to ensure that the product performance is completely consistent with the marked parameters.

Products Advantages
Extreme corrosion resistance, suitable for extreme working conditions
The chemical stability of tantalum metal far exceeds that of stainless steel and titanium alloy. It hardly corrodes in strong corrosive media such as hydrochloric acid, sulfuric acid, and nitric acid below 200 °C. It also has good resistance to special media such as water king and hydrofluoric acid (≤ 40%). ability. This feature makes our tantalum hexagon socket screws the first choice for chemical reactors, seawater desalination equipment, acid gas treatment systems, and other scenarios, effectively avoiding equipment leakage and safety hazards caused by corrosion failure of traditional fasteners.
High temperature stability to ensure long-term reliability
The melting point of tantalum is as high as 2996 °C, and it can still maintain stable mechanical properties in a high-temperature environment below 600 °C, without softening, deformation, or oxidation cracking problems. Compared with the limitation that ordinary carbon steel screws fail above 300 °C, our products can continue to work in high-temperature scenarios such as aerospace engine components and industrial furnace sealing structures, providing a guarantee for the long-term stable operation of equipment.
Customized capabilities to meet precise needs
We support full-process customization services and can adjust product size, thread specifications, surface treatment, and packaging methods according to the drawings or technical requirements provided by customers.
Compliance certification to reduce procurement risks
All products comply with ASTM B365, ISO 5832, and other international standards, and third-party material inspection reports can be provided. In highly regulated fields such as medical care and aerospace, compliance certification is a core consideration in procurement decisions. Our product qualifications can help customers successfully pass industry audits and reduce compliance risks.
Products Applications
Chemical and petrochemical industry
In core equipment such as chemical reactors, distillation columns, and pipeline flanges, tantalum hexagon socket screws can be used to connect corrosion-resistant liners and metal shells, maintain stable performance in strong corrosive media such as hydrochloric acid and sulfuric acid, and avoid equipment leakage, production accidents, and environmental risks.
Medical and pharmaceutical industry
Tantalum metal has excellent biocompatibility and is an ideal material for medical implants. Our tantalum hexagon socket screws can be used for the precision fixation of orthopedic implants, dental restorations, and surgical instruments without corroding or releasing harmful substances in the human body fluid environment. In pharmaceutical equipment, its corrosion resistance avoids the impact on the purity of the drug.
Aerospace and defence industry
In high-temperature and high-pressure scenarios such as aero-engines and satellite structural parts, tantalum hexagon socket screws can be used to fix superalloy parts, maintain stable mechanical strength in an environment below 600 °C, and provide a guarantee for the safe flight of aircraft. At the same time, its low density (16.68 g/cm ³) and high intensity ratio characteristics help to achieve lightweight equipment and improve fuel efficiency and load capacity.
Ocean and energy industry
In seawater desalination equipment, offshore platform pipelines, and deep-sea exploration instruments, our products can resist the corrosion of seawater and salt spray, and avoid structural failure caused by corrosion of traditional fasteners. In the field of nuclear power generation, tantalum has a low neutron absorption cross section, which can be used to connect internal components of reactors and maintain stable performance in radiation environments.
