A screw joint is a type of mechanical connection that uses a screw to hold two or more parts together. This method is commonly used in various applications, from furniture assembly to construction. The screw is threaded, allowing it to grip the materials tightly, providing a secure and stable connection. Screw joints can be easily assembled and disassembled, making them versatile for repairs and modifications. They are often preferred for their strength and reliability. Common types of screws used in these joints include wood screws, machine screws, and self-tapping screws, each designed for specific materials and applications.
