Product Description

DIN6921 EN 1665 Hex Flange Head Bolt With Serration Carbon Steel/Stainless Steel Class 8.8 /10.9

Characteristics

Unique Flange Design: Hex flange bolts feature a hexagonal flange at the bottom of the head. This flange distributes the clamping force over a wider area, reducing the stress concentration on the workpiece.
High Strength: Hex flange bolts are typically made from high-strength materials such as steel or stainless steel, ensuring durability and reliability in various applications.
Excellent Load Distribution: The flange design allows for more uniform load distribution compared to traditional bolts, resulting in less damage to the workpiece material.
Versatile Sizes: Hex flange bolts are available in various sizes and thread diameters to meet the needs of different applications.

Advantages

Reduced Stress Concentration: The flange design reduces stress concentration on the workpiece, preventing damage and cracks.
Increased Clamping Force: The wider flange provides a larger bearing surface, enabling a stronger clamping force to be applied.
Ease of Installation: Hex flange bolts can be easily tightened and loosened using standard hexagon tools.
Durable and Reliable: Made from high-strength materials, hex flange bolts are durable and reliable in demanding applications.

Application Scenarios

Metalworking and Fabrication: Hex flange bolts are commonly used in metalworking and fabrication processes to securely clamp and fix workpieces.
Machinery and Equipment: In machinery and equipment, hex flange bolts are used to connect and secure components, ensuring the stability and reliability of the overall system.
Construction and Bridge Building: In construction and bridge building, hex flange bolts provide a strong and reliable connection between steel components, ensuring the structural integrity of the structure.
Heavy Industry: Hex flange bolts are also widely used in heavy industry applications such as mining, oil and gas, and power generation, where high-strength and reliable connections are crucial.
