Fastening techniques are methods used to join two or more objects together securely. Common examples include using screws, nails, bolts, and adhesives. Each technique has its own advantages, such as ease of use, strength, and suitability for different materials like wood, metal, or plastic. In construction and manufacturing, choosing the right fastening technique is crucial for ensuring the durability and safety of structures and products. For instance, wood screws are ideal for woodworking, while welding is often used for metal fabrication. Understanding these techniques helps in selecting the best option for specific applications.
