Nailing is a construction technique that involves driving a metal fastener, known as a nail, into materials like wood or drywall. This process helps to join pieces together securely, providing structural integrity to various projects, from furniture to buildings. Nails come in different sizes and types, each designed for specific applications. The act of nailing can be done using a hammer or a nail gun, which automates the process for efficiency. Proper nailing techniques ensure that the materials are held firmly in place, reducing the risk of damage or failure in the structure.
