Which term refers to hardware items that have internal or external screw threads, such as screws, nuts and bolts?

• A. Threaded fasteners
• B. Adhesives
• C. Riveting
• D. Welding

Answer: (A)

Threaded fasteners are hardware items that use screw threads to create a join. Screws have external threads, nuts have internal threads, and bolts are threaded fasteners used with a nut or a tapped hole. This threading lets parts be clamped together and easily disassembled when needed. In contrast, adhesives create bonds without threads, rivets are permanent fasteners without threads, and welding joins by fusing materials, not by threading. So the term that best covers screws, nuts, and bolts is threaded fasteners.
