Stainless Steel Screws Suppliers

Stainless Steel Screws have excellent corrosion resistance and are suitable for wet and harsh environments.

In the modern industrial world, where durability, reliability, and longevity are essential, stainless steel screws have become a critical component in countless applications. Among their many advantages, one of the most notable is their excellent corrosion resistance, which makes them especially suitable for use in wet or harsh environments such as marine engineering, petrochemical plants, rail transit, and outdoor construction projects.

SS Screws are primarily made from high-quality alloys like SUS301, SUS304, and SUS316, all of which contain chromium—a key element that forms a passive oxide layer on the surface of the metal. This thin but highly effective layer protects the underlying material from oxidation and other forms of chemical degradation, even when exposed to moisture, saltwater, or aggressive chemicals. This inherent property allows stainless steel fasteners to maintain structural integrity and performance over long periods, significantly reducing maintenance costs and replacement frequency.

One company that has been at the forefront of manufacturing high-performance 304 Stainless Steel Screws is Jiangsu Jiajie Special Screw Co., Ltd. Established in 2008 with a registered capital of 50 million yuan, Jiangsu Jiajie has grown into a leading enterprise in the production of stainless steel products. Located in Dainan Town—often referred to as the "Stainless Steel Capital" of China—the company operates two facilities: a new plant covering 40,000 square meters and an older plant occupying 20,000 square meters. With its strategic location and state-of-the-art infrastructure, Jiangsu Jiajie has positioned itself as a reliable supplier for industries demanding high-quality fastening solutions.

The product portfolio of Jiangsu Jiajie Special Screw Co., Ltd. includes a wide variety of stainless steel fasteners such as external hexagonal screws, internal hexagonal screws, hexagonal nuts, washers, tapping screws, machine screws, tooth screws, flange fasteners, pipe fittings, non-standard fasteners, and stainless steel wire. These products are manufactured according to international standards including GB (Chinese), DIN (German), and ISO (International), ensuring compatibility and consistency across global markets.

Because of their superior corrosion resistance, stainless steel screws produced by Jiangsu Jiajie are widely used in industries that operate under extreme conditions. For example, in marine engineering, where exposure to saltwater can rapidly degrade standard fasteners, stainless steel screws offer long-term protection against rust and pitting. Similarly, in the photovoltaic industry, where solar panels are often installed in open fields or coastal areas, these fasteners provide the necessary strength and durability to withstand UV radiation, rain, and fluctuating temperatures.

In the petrochemical sector, 201 Stainless Steel Screws must endure constant exposure to corrosive gases and liquids. The use of high-grade materials like SUS316 ensures that the fasteners remain resistant to chloride-induced stress corrosion cracking—an issue that commonly affects less resilient metals. Likewise, in the rail transit industry, where trains and tracks are subject to vibrations, temperature extremes, and weathering, the robustness of stainless steel screws plays a crucial role in maintaining safety and operational efficiency.

Another important application area is the decoration and construction industry. In both indoor and outdoor architectural projects, aesthetics and longevity go hand in hand. Stainless steel screws not only enhance the visual appeal of structures but also ensure that installations remain secure and free from discoloration or degradation over time. Whether it’s fixing metal panels, assembling pergolas, or installing fixtures in bathrooms and kitchens, stainless steel fasteners offer peace of mind in terms of both appearance and performance.

Jiangsu Jiajie Special Screw Co., Ltd. produces approximately 80,000 tons of stainless steel fasteners annually, meeting the growing demand across various sectors. The company’s commitment to quality control, advanced manufacturing techniques, and customer-oriented service has earned it a solid reputation in both domestic and international markets. By continuously investing in research and development, the company ensures that its products meet evolving industry requirements and environmental standards.

316 Stainless Steel Screws are indispensable in environments where corrosion poses a significant threat to the lifespan and functionality of components. Their natural resistance to rust, chemical attack, and wear makes them ideal for challenging conditions ranging from offshore platforms to underground pipelines. As a trusted manufacturer, Jiangsu Jiajie Special Screw Co., Ltd. plays a vital role in supplying durable, high-performance fasteners that support the structural integrity and operational efficiency of critical infrastructure around the world. With its strong foundation, technical expertise, and dedication to excellence, the company continues to be a key player in the global stainless steel fastener market.
