Flange bolts are structural fasteners widely used in the fastener industry. They feature an integrated flange gasket structure at the bolt head, allowing them to replace traditional washers during installation. S-SEN manufacturers utilize their rational structural design and stable material processing technology to widely apply these bolts in applications such as machinery, building structures, automotive parts, and pipeline connections.
In practical applications, S-SEN Flange Bolts distribute pressure by expanding the contact surface, while reducing the need for additional washers, making installation simpler and more efficient. Whether for industrial equipment installation, steel structure connections, or machinery maintenance, Flange Bolts are a practical and common fastening solution.
As a structural fastener, S-SEN Flange Bolts combine the functions of a bolt and washer in a single structure, making installation more straightforward. During equipment connection, it reduces the number of parts, shortens installation time, and improves overall connection stability.
Flange bolts are fasteners that add a flange structure to a hexagonal head bolt. The flange is typically located at the bottom of the bolt head, forming a gasket-like contact surface.
This design offers several key advantages:
Increased contact area for stress distribution
Reduced need for additional gaskets
Improved installation efficiency
Provides some resistance to loosening in vibration environments
S-SEN Flange Bolts are designed with industrial application needs in mind, controlling dimensional accuracy and surface treatment to make them suitable for various mechanical and structural connection scenarios.
The flange structure is integrally molded with the bolt head, directly replacing traditional gaskets.
Advantages include:
Reduced assembly steps
Prevents gasket loss
Improved assembly efficiency
In mass production lines or large equipment installations, this design significantly simplifies operational processes.
The hexagonal head conforms to common industrial fastening standards and is compatible with standard tools:
Wrenches
Sockets
Pneumatic tools
This standard design makes S-SEN Flange Bolts more suitable for industrial mass assembly.
Common surface treatments include:
Galvanized
Zinc-nickel plating
Blackening
Stainless steel
These treatments help improve corrosion resistance, allowing Flange Bolts to be used outdoors or in humid environments.
Some models feature a serrated flange structure, which increases friction and reduces the risk of loosening in vibrating environments.
Suitable applications include:
Automotive assembly
Industrial equipment
Heavy machinery
The flange expands the stress area, allowing for a more even distribution of tightening pressure across the connection surface.
This is especially important for the following materials:
Aluminum
Steel
Wood Structures
Composite Materials
The serrated flange version maintains a stable connection under vibration, reducing the possibility of bolt loosening.
Eliminating the need for additional washers reduces installation steps.
This improves overall efficiency in equipment maintenance or mass assembly.
Through strict dimensional control, S-SEN Flange Bolts achieve a stable fit with the connectors, improving the overall reliability of the connection structure.
