What is the difference between a rivet and a bolt in sheet metal joints?

• A. A rivet forms a permanent joint; a bolt is removable
• B. A rivet forms a removable joint; a bolt forms permanent
• C. Both form permanent joints
• D. Bolts are used only in wood

Answer: (A)

In sheet metal joints, the way the fastener holds the pieces together defines how the joint behaves over time. A rivet joins by deforming its shank to create a second head, which clamps the two sheets together without relying on threads. Once the rivet is set, the joint becomes essentially permanent because you don’t have a threaded path to loosen or re-tighten. In contrast, bolts pass through holes and are secured with a nut, using threads to hold them in place. This threaded connection can be loosened and removed, allowing the joint to be disassembled and reassembled as needed. So the principal difference is that rivets form a permanent connection, while bolts provide a removable connection.
