Product Description:
The Bolts and Nuts product line offers a versatile and reliable fastening solution engineered to meet the highest standards of industrial applications. Featuring a robust hex head design, these fasteners provide excellent torque transfer and ease of installation, making them ideal for a wide range of mechanical and structural uses. With a strength grade of 4, these bolts and nuts deliver dependable performance in demanding environments, ensuring secure and long-lasting joints.
Available in a size range from M3 to M24, this product line caters to diverse assembly needs, from small precision components to larger structural connections. The outer diameter of 40mm provides a substantial bearing surface, enhancing load distribution and minimizing wear and deformation under stress. Additionally, the specific variant M42 * 3* 280mm addresses specialized requirements where longer bolt lengths and precise threading are essential for secure fastening.
One of the standout features of this product collection is the use of super duplex stainless steel bolts S32750 / S32760. These materials are renowned for their exceptional strength, corrosion resistance, and durability, making them suitable for harsh environments and critical applications. Super duplex stainless steel combines the best properties of austenitic and ferritic stainless steels, delivering superior resistance to stress corrosion cracking and pitting, which are common challenges in aggressive chemical and marine settings.
In addition to material excellence, these bolts and nuts comply with ASTM A320 L7M low temperature bolting standards, ensuring reliable performance even in sub-zero conditions. The impact-tested certification guarantees that the fasteners maintain their toughness and integrity under low temperature scenarios, which is vital for applications in cold climates, cryogenic systems, and other environments where thermal contraction and brittleness could compromise safety.
Furthermore, the product range includes stud bolt and nut sets designed specifically for ASME B16.5 flanges. These sets are precision-engineered to provide optimal compatibility and sealing performance in piping systems, pressure vessels, and industrial equipment. Using stud bolts and nuts that conform to ASME B16.5 flange standards ensures that the assembly meets industry requirements for pressure containment, mechanical strength, and leak prevention.
The hex head design of these bolts allows for easy and secure tightening using standard tools, facilitating efficient assembly and maintenance operations. The strength grade 4 classification offers a balanced combination of tensile strength and ductility, suitable for general applications where moderate mechanical loads are encountered. The broad size range from M3 to M24 allows these fasteners to be used across multiple sectors, including automotive, construction, manufacturing, and energy industries.
With an outer diameter of 40mm, these bolts provide a robust connection point capable of withstanding significant forces. The specific dimension of M42 * 3* 280mm indicates a large bolt size with fine threading, ideal for heavy-duty applications requiring precise alignment and secure fastening over extended lengths. This makes the product well-suited for infrastructure projects, heavy machinery assembly, and other scenarios demanding high-performance fasteners.
In summary, the Bolts and Nuts product range featuring hex head fasteners, strength grade 4, and sizes from M3 to M24, with an outer diameter of 40mm and specific M42 * 3* 280mm options, represents a comprehensive solution for various industrial fastening needs. The incorporation of super duplex stainless steel bolts S32750 / S32760 ensures outstanding corrosion resistance and mechanical strength, while compliance with ASTM A320 L7M low temperature bolting standards guarantees reliable performance in cold environments. Additionally, the availability of stud bolt and nut sets for ASME B16.5 flanges provides tailored solutions for piping and pressure vessel applications, making this product line an essential choice for engineers and procurement specialists aiming for quality, durability, and safety in their fastening components.

Applications:
Bolts and nuts are essential fastening components used across a wide range of industries and applications. Our product range includes hot dip galvanized (HDG) bolts and nuts grade 8.8, ASTM A449 high strength carbon steel hex bolts, and DIN 912 socket head cap screws class 12.9, ensuring high quality and reliability in every use. These fasteners come with nuts per bolt options of 2 or 3, providing versatility to suit different assembly requirements.
The size range of our bolts and nuts spans from M3 to M24, catering to both small precision applications and larger structural projects. This comprehensive size variety makes them ideal for use in automotive, construction, machinery, and electrical industries where different dimensions are critical to performance and safety.
One of the key advantages of our bolts and nuts is their 100% tested quality, ensuring that each piece meets stringent standards for strength and durability. The high strength grade 4 classification guarantees that the fasteners can withstand significant mechanical stress, making them ideal for heavy-duty applications. This is particularly important in structural engineering, bridge construction, and industrial equipment assembly, where failure is not an option.
Corrosion resistance is another vital attribute of our product line. The hot dip galvanized (HDG) coating on our bolts and nuts protects them from rust and environmental degradation, making them suitable for outdoor and marine environments. This corrosion resistance extends the lifespan of the fasteners and reduces maintenance costs, especially in harsh conditions such as chemical plants, offshore platforms, and outdoor infrastructure projects.
Applications of these bolts and nuts include assembling machinery, securing automotive parts, constructing steel frameworks, and fastening components in electrical panels. The ASTM A449 high strength carbon steel hex bolts are particularly favored in automotive and heavy machinery due to their toughness and reliability. Meanwhile, the DIN 912 socket head cap screws class 12.9 are perfect for precision engineering applications requiring high torque and tight fastening.
In summary, our bolts and nuts with options of 2 or 3 nuts per bolt, available from M3 to M24 sizes, and featuring high strength grade 4 and corrosion resistance, are versatile fasteners suitable for a wide range of industrial, construction, and mechanical applications.
