Why choose flange bolts with serrated hex washers? The serrations bite into the base material to reduce loosening from vibration, while the flange distributes clamping force to protect surfaces from damage and prevent pull-through. Zinc coating adds long-lasting corrosion resistance, making these bolts ideal for both indoor and outdoor environments.
