Screw fastening is a method of joining two or more materials together using a screw. A screw is a type of fastener that has a helical ridge, known as a thread, which allows it to be driven into materials like wood, metal, or plastic. This creates a strong connection that can be easily tightened or loosened, making it a popular choice in construction and manufacturing. The process of screw fastening involves using a screwdriver or a power tool to insert the screw into the materials. The design of the screw helps it grip the material securely, providing stability and strength. This technique is widely used in furniture assembly, automotive applications, and various DIY projects.
