Hex Flange Bolts are typically used for automotive and construction applications. The flange directly underneath the hexagon-shaped head is designed to distribute the load and help protect the surface beneath, and eliminates the potential need for a washer.

 

The main difference between a hex bolt and a hex flange bolt lies in the head design: a hex bolt has a standard hexagonal head and usually requires a washer to distribute pressure, whereas a flange bolt has an integrated flange under the head that acts like a built-in washer, increasing the contact area and distributing pressure directly. This makes hex flange bolt easier to install and provides a more stable fastening without the need for additional washers.

Advantages Of Hexagon Flange Bolt

---

 

1. Simplified Installation: The flange acts as a built-in washer, allowing hexagon flange bolts to be used directly without the need for additional washers, thereby simplifying the installation process.

2. Better Pressure Distribution: The flange increases the contact area between the bolt head and the material, which helps to evenly distribute pressure, reducing the risk of material deformation or damage.

3. Anti-Loosening Performance: Some hexagon flange bolts feature serrations on the flange surface, which increase friction and effectively prevent the bolt from loosening in vibrating or impact-prone environments.

4. High Strength: Hexagon flange bolts are typically made from high-strength materials, enabling them to withstand significant torque and load, making them suitable for applications requiring high stability and safety.

5. Corrosion Resistance: AYA hexagon flange bolts are crafted from premium materials and produced using advanced manufacturing processes, ensuring excellent corrosion resistance and long-lasting stability and reliability in harsh environments.

6. Wide Application: Due to their outstanding performance and versatility, hexagon flange bolts are widely used in automotive, construction, and machinery industries, particularly in applications that require strong and durable connections.
