Core Features of Hexagon Flange Bolts with Serrated
- Hexagon head design: Facilitates efficient torque transmission with standard wrenches, ensuring convenient and secure installation
- Serrated flange feature: Sharp serrations on the flange surface bite into the workpiece during tightening, preventing bolt rotation and significantly improving anti-loosening performance, especially in high-vibration environments
- Integrated flange function: Acts as a built-in washer to evenly distribute clamping force, reduce surface pressure on workpieces, and avoid local deformation or damage
- Excellent mechanical properties: High load-bearing capacity, shear strength, and wear resistance, ensuring stable and reliable connections under long-term dynamic loads
