Which technique uses mechanical fasteners rather than heat or adhesives to join pieces?

• A. Riveting
• B. Soldering
• C. Adhesives
• D. Welding

Answer: (A)

The main idea here is joining parts with a fastener that clamps them together without melting or bonding. Riveting does exactly that: a rivet is inserted through holes in the pieces and then deformed at the back to form a second head, pulling the parts tight. The joint is held by the mechanical fastener itself, not by melted metal or glue. Soldering and welding rely on heat to join pieces, while adhesives rely on bonding agents, so they’re not mechanical fasteners. Riveting is the technique that uses mechanical fasteners to join pieces.
