Hex Serrated Flange Bolt is a hexagonal head bolt with flange and serrations. The hexagonal head design facilitates installation and removal using a wrench or other tools. The flange surface expanded below the bolt head increases the contact area, thereby dispersing pressure and reducing damage to the connecting materials. The serration design on the flange surface can increase friction and prevent the bolt from loosening under vibration or other external forces. This bolt is often used in applications that require high strength and anti-loosening, such as automobiles, mechanical equipment and construction projects.
