Product Description:
The Bolts and Nuts product is a premium fastening solution designed to meet the highest industry standards and provide exceptional performance in various applications. Manufactured with meticulous attention to detail, these components are crafted from ISO 898-1 class 10.9 alloy steel bolts paired with grade 10 nuts, ensuring superior strength, durability, and reliability. The bolts and nuts are perfect for demanding environments where high strength and secure locking are essential.
One of the standout features of these bolts and nuts is their high strength performance. The bolts are forged using advanced forging processes that enhance their structural integrity and toughness, making them capable of withstanding significant mechanical stresses. The nuts are also designed to complement the bolts perfectly, providing a secure fit that maintains the fastening even under vibration or dynamic loads. This high strength capability is critical for applications in construction, machinery, automotive, and heavy equipment industries.
The product range includes hot dip galvanized (HDG) bolts and nuts with a grade 8.8 rating, offering excellent corrosion resistance. This coating process applies a thick layer of zinc to the surface, protecting the bolts and nuts from rust and environmental degradation, which is particularly beneficial in outdoor or harsh environments. Additionally, the assortment features DIN 931 and DIN 933 hex bolts with an 8.8 zinc plating. These zinc-plated bolts provide a balance of aesthetic appeal and corrosion protection, making them suitable for both industrial and decorative purposes.
The outer diameter of the bolts measures 40mm, providing a robust and substantial fastening solution capable of handling heavy loads. This dimension ensures compatibility with a wide range of nuts and washers, facilitating easy and secure installation. The 40mm outer diameter also contributes to the overall mechanical strength and stability of the bolted joint, making it ideal for structural applications.
Another critical attribute of these bolts and nuts is their self-locking mechanism. This feature prevents loosening caused by vibrations or dynamic forces, which is a common challenge in many mechanical assemblies. The self-locking design eliminates the need for additional locking devices, simplifying installation and maintenance while enhancing safety and reliability. Whether used in machinery, automotive assemblies, or construction frameworks, the self-locking bolts and nuts provide peace of mind and long-lasting performance.
The packing of these bolts and nuts in sturdy wooden cases ensures safe transportation and storage. The wooden case packaging protects the products from physical damage, moisture, and contamination during transit and handling. This thoughtful packaging approach preserves the quality and integrity of the bolts and nuts until they reach the end user, making it a preferred choice for bulk orders and industrial supply chains.
In summary, the Bolts and Nuts product combines high-strength ISO 898-1 class 10.9 alloy steel bolts with grade 10 nuts, hot dip galvanized grade 8.8 bolts and nuts, and DIN 931 / DIN 933 hex bolts 8.8 zinc plated to deliver a comprehensive fastening solution. With a 40mm outer diameter, forged construction, self-locking mechanism, and reliable wooden case packing, this product meets rigorous performance and durability requirements across various industries. Whether for structural applications, heavy machinery, or general industrial use, these bolts and nuts provide unmatched quality, strength, and security.

Applications:
The bolts and nuts with a total length of 70 mm are specifically designed for mechanical assembly applications that demand high strength and reliability. These fasteners come with three nuts per bolt, ensuring secure and stable connections in various industrial and structural settings. The product specifications include M42 * 3 * 280mm dimensions, making them suitable for heavy-duty mechanical joints where precision and durability are critical.
These bolts and nuts are manufactured to meet high-quality standards, with quality levels rated at 10.9 and 12.9. Such grades indicate exceptional tensile strength and toughness, making them ideal for applications subjected to significant stress and load. The use of EN 14399-1 HV 10.9 preloaded structural bolting assemblies ensures that the fasteners provide excellent preload control, which is essential in structural steelwork to prevent loosening and maintain joint integrity under dynamic conditions.
In environments requiring enhanced corrosion resistance and durability, the duplex stainless steel bolts and nuts S31803 version of this product is an excellent choice. Duplex stainless steel combines the benefits of austenitic and ferritic stainless steels, offering superior resistance to stress corrosion cracking and high mechanical strength. This makes them suitable for chemical processing equipment, offshore structures, and marine applications where exposure to corrosive agents is common.
For applications involving low temperatures, ASTM A320 B8 Class 1 stainless steel bolts are utilized. These bolts are engineered to perform reliably under sub-zero conditions, maintaining mechanical properties without becoming brittle. This characteristic is crucial in cryogenic environments, refrigeration systems, and cold storage facilities, where standard fasteners may fail.
Overall, these bolts and nuts are versatile components widely used in construction, heavy machinery, automotive assembly, and infrastructure projects. Their design and material composition make them ideal for occasions requiring high preload, excellent corrosion resistance, and robust mechanical performance. Whether in industrial plants, offshore platforms, or critical mechanical assemblies, these fasteners provide dependable performance and long-term reliability.
