Product Description

Product Description:

The Bolts and Nuts product line offers a superior fastening solution designed to meet the highest standards of industrial and structural applications. Manufactured with a focus on strength, durability, and corrosion resistance, these assemblies provide exceptional performance in demanding environments. Each unit is composed of a bolt, nut, washer, and sealing ring, ensuring a comprehensive fastening system that delivers reliability and safety in every installation.

One of the standout features of these bolts and nuts is their high strength, with a tensile strength (σb) of at least 450 MPa. This high strength is achieved through precision forging processes and the utilization of premium-grade material, specifically 25CRMO4. This alloy is known for its excellent mechanical properties, providing robustness and toughness that can withstand heavy loads and extreme conditions without compromising structural integrity. The forging and high-strength processing techniques further enhance the mechanical performance, ensuring each component meets rigorous quality standards.

Corrosion resistance is another critical attribute of this product series. The materials and coatings used in manufacturing provide high resistance to corrosion, making these bolts and nuts ideal for outdoor, marine, and chemically aggressive environments. This ensures longevity and reduces maintenance costs by preventing rust and degradation over time, which is especially important in structural applications where safety and durability cannot be compromised.

These bolts and nuts are designed in compliance with internationally recognized standards, making them suitable for a wide range of applications. They align with EN 15048-1 non-preloaded structural bolting assemblies 8.8, a specification that defines requirements for high-quality structural fasteners without preloading. Additionally, the product is comparable to A193 B7 hex bolts paired with A194 2H heavy hex nuts, both of which are commonly used in pressure vessels, piping, and other high-stress environments. The bolts and nuts also meet the ISO 898-1 class 8.8 classification for high tensile bolts and nuts, ensuring compatibility and interchangeability with other components in this category.

The combination of these standards and material specifications guarantees that this product line is suitable for critical applications such as construction, heavy machinery, automotive, oil and gas, and other industrial sectors. The one bolt unit concept, which includes the bolt, nut, washer, and sealing ring, simplifies procurement and installation processes, providing users with a ready-to-use assembly that ensures optimal performance and ease of use.

In summary, the Bolts and Nuts product delivers a high-strength, corrosion-resistant fastening solution manufactured from premium 25CRMO4 material using advanced forging techniques. Its compliance with EN 15048-1, A193 B7/A194 2H, and ISO 898-1 class 8.8 standards underscores its suitability for high-demand structural and industrial applications. Whether used in construction, manufacturing, or maintenance, these bolts and nuts provide reliable, durable, and high-performance fastening that meets the most stringent industry requirements.

Applications:

Bolts and nuts are essential components in a wide range of industries and applications, serving as the backbone of mechanical fastening solutions. The bolts and nuts with a cap diameter of 12 mm, customizable insert diameter, and a length of 30 mm are designed to meet diverse application needs with high precision. These fasteners offer a thread tolerance of 0.02, ensuring a secure and reliable fit, which is critical for maintaining structural integrity in various scenarios.

One of the primary application occasions for these bolts and nuts is in industrial machinery assembly, where durability and precision are paramount. The ability to customize the body type and insert diameter allows these fasteners to be tailored specifically to the requirements of different machines, enhancing performance and safety. For example, DIN 931 / DIN 933 hex bolts 8.8 zinc plated are widely used in construction and manufacturing sectors, offering excellent corrosion resistance and mechanical strength, suitable for both indoor and outdoor environments.

In addition, these bolts are ideal for use in environments requiring specialized material properties. ASTM A320 L7M low temperature bolting, which is impact tested, is specifically designed for applications in low-temperature conditions such as cryogenic equipment, refrigeration systems, and cold storage facilities. This ensures that the bolts maintain their toughness and structural integrity even under extreme cold, preventing failures that could lead to costly downtime or safety hazards.

Moreover, ASTM A307 Grade B carbon steel bolts are commonly employed in general-purpose applications where moderate strength and durability are needed. These bolts are frequently used in automotive repair, construction, and maintenance tasks, offering a cost-effective solution without compromising on quality. The zinc plating on the DIN 931 / DIN 933 hex bolts further enhances resistance to rust and corrosion, making them suitable for outdoor uses and harsh weather conditions.

The customizable features of these bolts and nuts, including the insert diameter and body type, allow engineers and designers to select the most appropriate configuration for specific projects. Whether it is heavy machinery assembly, infrastructure development, or specialized low-temperature applications, these bolts and nuts provide the versatility and reliability needed. Their precise thread tolerance of 0.02 ensures compatibility with a wide range of nuts and components, facilitating smooth installation and long-term performance.

In summary, bolts and nuts with a 12 mm cap diameter, customizable insert diameter and body type, 30 mm length, and a tight thread tolerance of 0.02 are indispensable in numerous application occasions. From the robust DIN 931 / DIN 933 hex bolts 8.8 zinc plated used in construction to the impact-tested ASTM A320 L7M low temperature bolting and the versatile ASTM A307 Grade B carbon steel bolts, these fasteners are engineered to deliver strength, durability, and reliability across various scenarios.
