Threaded connections are a type of mechanical fastening used to join two or more components together. They typically involve a screw or bolt that has a helical ridge, known as a thread, which allows it to be screwed into a corresponding hole or nut. This design provides a strong and secure connection, making it widely used in various applications, from household items to industrial machinery. These connections can be found in many everyday objects, such as furniture, automobiles, and electronic devices. The ability to easily tighten or loosen threaded connections makes them convenient for assembly and disassembly, allowing for repairs or modifications without damaging the components involved.
