Hex bolts are fasteners with a hexagonal head, designed to be tightened or loosened using a wrench. They are commonly made from materials like steel or stainless steel, providing strength and durability for various applications. The threaded shaft allows for secure connections, making them ideal for construction, machinery, and automotive uses. These bolts come in various sizes and grades, which indicate their strength and suitability for different tasks. Hex bolts are often used with nuts to create a strong joint, and they can be found in many everyday items, from furniture to large industrial equipment.
