Hex head bolts are a type of fastener characterized by their six-sided (hexagonal) head, which allows for easy gripping and torque application using a wrench. Typically made from materials like carbon steel, stainless steel, or alloy steel, these bolts come in various sizes and grades, each designed to meet specific strength and durability requirements. The hexagonal shape of the head provides a larger surface area for handling, making it easier to achieve the necessary clamping force when tightening.
