Why Choose Hex Flange Bolts?
- 🔩 Load Distribution: The flange spreads the load over a wider area, protecting the surface beneath the bolt.
- 🔒 Reduced Loosening: Integrated flange minimizes the risk of the bolt loosening over time, ensuring joint stability.
- 🔧 Elimination of Washers: Simplifies assembly by removing the need for separate washers.
- 💎 Durability: Flanged fasteners are more resistant to deformation and maintain clamp force better than standard washers.
- 💪 Enhanced Load Bearing: Distributes load evenly to prevent surface damage.
- 🔧 Improved Joint Integrity: Maintains consistent preload, reducing joint failure risks.
- ⏱️ Time-Saving: Eliminates the need for additional washers, streamlining assembly.
Hex Flange Screws vs. Standard Screws with Washers
| Feature | Hex Flange Screws | Standard Screws with Washers |
|---|---|---|
| Load Distribution | Integrated flange spreads load evenly | Separate washers required |
| Loosening Risk | Minimized with flange design | Higher risk without additional locking mechanisms |
| Assembly Efficiency | Simplified without needing washers | Requires additional washers |
| Durability | More resistant to deformation | Washers can deform under high stress |
Benefits of Hex Flange Bolts

Technical Insights
Hex flange screws eliminate the need for traditional washers by integrating a flange that distributes load and minimizes surface damage. This design enhances torque-tension characteristics, ensuring consistent preload and reducing joint failure risks. Unlike standard washers, flanged screws resist plastic deformation under high compressive stress, maintaining clamp force and joint integrity even in short grip length joints.
