Product Description:
The Bolts and Nuts product is engineered to meet the highest standards of performance and durability, making it an ideal choice for demanding industrial applications. These bolts and nuts are manufactured with a metric thread type, specifically designed to ensure precise fitting and secure fastening in various mechanical and structural assemblies. The specific dimensions of the bolts are M42 * 3 * 280mm, providing robust and reliable connections where strength and stability are critical.
One of the standout features of this product is its high strength performance. These bolts are classified as ASTM A490 high strength structural bolts, which means they conform to stringent standards for mechanical properties and quality. ASTM A490 bolts are widely recognized for their ability to withstand heavy loads and harsh operating conditions, making them suitable for structural steel joints, heavy machinery, and infrastructure projects where safety and integrity are paramount.
The material composition of these bolts and nuts further enhances their strength and corrosion resistance. They are made from super duplex stainless steel grades S32750 and S32760, which are known for their exceptional mechanical properties and superior resistance to corrosion in aggressive environments. Super duplex stainless steel bolts S32750 / S32760 offer an excellent combination of high tensile strength and toughness, along with outstanding resistance to pitting, crevice corrosion, and stress corrosion cracking. This makes them particularly suited for use in marine, chemical processing, and petrochemical industries where exposure to corrosive agents is common.
In addition to the bolts themselves, the product package includes nuts designed to complement the bolts perfectly. Each bolt is accompanied by three nuts, ensuring that users have adequate fastening components for their assembly needs. This nuts per bolt ratio is carefully selected to provide optimal clamping force and stability, which is essential for maintaining the integrity of the connection under dynamic loads and vibrations.
The packing of the bolts and nuts is done thoughtfully to ensure safe transportation and storage. The entire set is securely packed in a wooden case, which offers excellent protection against physical damage and environmental factors during shipping. Wooden case packaging also facilitates easier handling and stacking in warehouses or on construction sites, thus preserving the quality and condition of the product until it reaches the end user.
Overall, the Bolts and Nuts product featuring metric thread type, high strength performance, and specific dimensions of M42 * 3 * 280mm represents a reliable and durable fastening solution. Its compliance with ASTM A490 high strength structural bolts standards and the use of super duplex stainless steel bolts S32750 / S32760 material ensures that it meets the rigorous demands of industrial and structural applications. Whether for heavy construction, machinery assembly, or corrosive environment projects, this product delivers exceptional performance, safety, and longevity.
Choosing these bolts and nuts means investing in quality components that uphold the highest standards of engineering and manufacturing. The combination of metric threading, high tensile strength, and corrosion resistance makes them versatile and dependable for a wide range of uses. With the added assurance of secure wooden case packaging and the inclusion of three nuts per bolt, customers can be confident in the product’s ability to perform consistently and withstand challenging conditions over time.
