Drywall screws are specialized fasteners designed for affixing drywall sheets to wooden or metal studs. Unlike regular screws, drywall screws are engineered to prevent tearing of the drywall paper and to provide superior grip. They typically feature a bugle head that reduces the risk of tearing and a sharp drill point that makes installation easier. The market offers various types of drywall screws, including coarse-thread screws for wood and fine-thread screws for metal.

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.

Size and dimension specifications are equally important. Bolt diameter and length are determined by the load-bearing requirements of the structure and the type of soil it's embedded in. Generally, bolt diameters range from 1/2 inch to 1-1/2 inches, while lengths can vary from a few inches to several feet. The American Institute of Steel Construction (AISC) and International Building Code (IBC) provide detailed guidelines for these dimensions.
