What is the primary purpose of using nails in constructions?

The primary purpose of using nails in construction is to join wood or other materials together. Nails provide a simple yet effective means of fastening different components, such as framing members, sheathing, and finishes, which is crucial in ensuring the structural integrity of buildings and other constructions. The design of a nail, typically featuring a sharp point and a head, allows it to penetrate materials easily and hold them securely in place. This fastening method is favored for its reliability, ease of use, and speed, making it a fundamental practice in a variety of construction applications.
