The heavy hex head bolt consists of a threaded shank and a large hexagonal head, which provides a larger surface area for better grip and torque transmission. The head design also prevents the bolt from turning during installation, ensuring a secure fit. The thread pitch and diameter of the bolt are crucial factors that determine its mechanical properties, such as tensile strength and shear strength. Generally, heavier bolts have greater strength due to their increased material volume.
