Rotating tools are used to assemble parts that are connected by which means?

Rotating tools are typically used to install threaded fasteners. These tools, such as drills, impact drivers, and wrenches, facilitate the process of turning bolts and screws which are designed with external threads that fit into corresponding internal threads on nuts or tapped holes. The engagement of these threads allows for secure and adjustable connections between components.

Threaded fasteners are favored in construction and mechanical assembly because they allow for easier disassembly and reassembly, which is often required in maintenance or repairs. Additionally, they can redistribute stress more evenly across a joint, providing a reliable connection under various loads and conditions.

Other fastening methods, such as rivets, nails, and welds, have their own specific applications and tools. Rivets and nails are typically driven into materials without the need for rotation, while welds create a permanent bond through the melting and fusion of materials. These methods do not usually involve the same tools or techniques associated with assembling threaded fasteners.
