Customized Hexagon Socket Bolts for Generators

The hex socket bolt (also known as a socket head cap screw) is a vital fastener, indispensable across various applications in power plants. Its specialized design offers distinct advantages in performance, space efficiency, and maintenance.

1. Essential Functions of Hexagon Socket Bolts

These bolts are valued for their reliability and clever design features:

• Secure Fastening Connection: The primary function is to securely join two or more components. Through the cooperation of threads and a nut, the bolt provides a stable fastening force, ensuring components remain tightly secured, even during continuous operation.
• Space Saving Design: The head of a hex socket bolt features an internal hexagonal drive, allowing the entire bolt head to be recessed or counter-sunk into the component. This crucial feature saves valuable space, making hex socket bolts ideal for applications where compact assembly is necessary.
• Enhanced Anti-Loosening Function: When paired with specialized anti-loosening nuts or washers, hex socket bolts significantly enhance joint reliability. This design effectively prevents the bolt from loosening in environments with significant vibration or impact, guaranteeing connection stability.
• Easy to Install and Remove: Hex socket bolts are installed and removed using a simple hex key (Allen wrench). This tool is compact and easy to maneuver, making these bolts particularly suitable for maintenance and repair work in confined or hard-to-reach spaces.

2. Key Application Locations in Power Plants

The unique features of hex socket bolts make them suitable for diverse applications in power generation facilities:

• Equipment Assembly: Due to their excellent fastening strength and ease of installation, hex socket bolts are frequently used in the assembly of critical equipment, including generators, turbines, and boiler components.
• Pipe Connections: In the extensive piping systems of power plants, these bolts are used for flange connections, providing a reliable and stable seal. Their design facilitates easy removal and re-tightening during maintenance.
• Maintenance and Replacement: During routine maintenance and equipment overhauls, bolts often require removal and replacement. The internal drive design of the hex socket bolt makes disassembly and installation faster and more convenient, reducing overall maintenance difficulty and cost.

3. Materials and Performance Requirements

Hex socket bolts used in power generation must meet stringent material and performance standards:

• Material Selection: These bolts are typically crafted from high-strength alloy steels such as 15CrMoA, 35CrMoA, 12Cr1MoV, 25Cr2MoVA, 38CrMOA1A, 20Cr3MoWVA, 20CR1MO1VNBTIB, 40CRNIMOA, 42CrMoA, 45Cr1MoV, and 12Cr2Mo1. These materials ensure superior mechanical strength and heat resistance.
• Performance Grades: Performance grades, including 4.8, 8.8, and 10.9, reflect the bolt's guaranteed tensile and yield strength. For example, a Grade 8.8 bolt has a tensile strength of 800 MPa and a yield strength of 640 MPa.
• Surface Treatment: To combat the harsh industrial environment, hex socket bolts often undergo surface treatments like electroplating, blackening, or oxidation to enhance their corrosion resistance and wear durability.
