At its core, the structure of a bolt consists of a few key components the head, the shank, and the threads. The head is the larger, often hexagonal or square part at one end of the bolt, designed to provide a surface for the application of torque when tightening or loosening the bolt with a wrench. The shank is the long cylindrical part that spans between the head and the threads, and it determines the overall length of the bolt. The threads are helical ridges that spiral around the shank, allowing the bolt to engage with a nut or a threaded hole, enabling a strong clamping force between joined parts.
