What materials can screw fasteners join?

Screw fasteners are versatile mechanical components that can join a wide range of materials, making them an essential choice in engineering and construction. The correct answer indicates that they can effectively join various materials, including metal and wood.

Screws are designed to create a strong connection through their helical thread, which allows them to grip materials tightly. This capability enables screws to join two or more components made from different materials, such as metal and wood, or even combinations that include plastic. The design of screw fasteners allows them to provide a secure hold, which is crucial for structural integrity in many applications.

What enhances their versatility further is the availability of different types of screws, specifically engineered for particular materials. For instance, wood screws have a coarse thread designed for gripping into wood fibers, while machine screws are intended for use with metal components. This adaptability makes screws a preferred choice for various assembly tasks across numerous industries.

While other options are limited to specific materials, the ability of screw fasteners to connect multiple types illustrates their importance in engineering practices.
