Our Stainless Steel Product Range

We offer a complete line of stainless steel fasteners and components, each designed for specific performance requirements. The table below outlines our primary product categories and their typical applications.

We also supply aluminum, brass, and titanium alloy products for specialized requirements. For non-standard components, our engineering team works from your drawings to produce custom fasteners and stampings.

Application Fit and Material Selection

Choosing the right stainless steel grade is critical for corrosion resistance, strength, and longevity. We commonly work with austenitic grades like 304 and 316, which offer excellent formability and weldability. For more demanding environments, we supply duplex grades such as 2205 and 2507, which provide higher strength and superior resistance to chloride stress corrosion cracking.

Our engineering team helps you match the material to the working environment—whether it's marine, chemical processing, food handling, or outdoor construction. We consider factors like temperature, exposure to chemicals, and mechanical loads to recommend the optimal grade.

Critical Specifications and Sizing

Our stainless steel fasteners are available in a wide range of sizes, from M2 to M30 in diameter and lengths from 4mm to 500mm. We manufacture to DIN, IFI, ANSI, and GB standards, ensuring dimensional accuracy and thread compatibility.

• Thread types: Metric coarse and fine, UNC/UNF, and custom profiles.
• Head styles: Hex, socket, pan, countersunk, flange, and more.
• Drive systems: Phillips, slotted, hex, Torx, and custom drives.
• Surface finishes: Plain, passivated, polished, or coated as required.

For non-standard parts, we can produce custom threads, lengths, and head geometries to meet your exact specifications.

Quality Assurance and Testing

Quality is built into every step of our manufacturing process. We operate our own laboratory equipped with advanced inspection tools, and we use optical sorting technology to ensure that every part meets dimensional and visual standards. Our quality management system is certified to ISO9001:2000, and we continuously monitor production to maintain consistency.

We perform mechanical testing, including tensile and hardness tests, as well as corrosion resistance checks when required. For critical applications, we can provide material certificates and test reports.

Customization and Engineering Support

Our R&D team has over 10 professional and technical personnel dedicated to developing custom solutions. Whether you need a non-standard screw, a special bolt, or a complex stamped part, we can produce it from your drawings or samples. We also offer design assistance to optimize manufacturability and performance.

We support OEM and ODM projects, and we can handle everything from material selection to packaging and delivery.

Information We Use to Configure Your Solution

To prepare an accurate quotation and production plan, we need the following details from you:

• Product type: Screw, bolt, nut, stamping, or custom part.
• Material grade: e.g., 304, 316, 2205, or other.
• Dimensions: Diameter, length, thread pitch, and head style.
• Standard: DIN, ANSI, GB, BS, or non-standard.
• Quantity: Estimated annual or per-order volume.
• Application: Environment, load requirements, and any special testing needs.

With this information, we can recommend the most cost-effective material and manufacturing approach, and provide a detailed proposal.
