river
Old French
“A rivet holds two things together permanently — and the word comes from the Old French for 'to fix,' which also gave English the word 'river' for a watercourse fixed in its banks.”
Rivet comes from Old French river (to fix, to attach, to fasten to a bank), possibly from rive (a bank, a shore). The connection between riverbanks and rivets is the idea of fixing in place: a river is fixed between its banks; a rivet is fixed through its plates. The etymology is debated, but the metaphor is consistent. Both meanings are about things that hold fast.
Riveting is an ancient joining technique. Bronze rivets appear in Egyptian and Mesopotamian metalwork from before 3000 BCE. The principle is simple: a metal pin is pushed through aligned holes in two plates, and the protruding end is hammered flat (or 'bucked') to create a permanent mechanical joint. Unlike a bolt, which can be removed, a rivet is permanent. You have to drill it out to undo it.
The Eiffel Tower contains 2.5 million rivets. The Titanic had approximately 3 million. The Golden Gate Bridge has approximately 600,000. Before welding became reliable in the mid-twentieth century, riveting was the primary method for joining structural steel. Teams of riveters — a heater, a catcher, a bucker, and a driver — worked in coordinated four-person crews, throwing red-hot rivets from forge to worker with tongs.
The verb 'to rivet' means to fix attention — to be riveted is to be unable to look away. This figurative sense appeared by the 1600s. The connection is the rivet's permanence: once you are riveted, you are held in place. A riveting performance, a riveting story, a riveting speaker. The tool that holds steel holds attention.

Rivets have been largely replaced by welding in structural steel work. But riveted joints still appear in aircraft construction (where different metals must be joined without heat distortion), in some bridge construction, and in clothing (jeans pockets are reinforced with copper rivets, a technique patented by Jacob Davis and Levi Strauss in 1873).
The word survives better than the technique. Riveting is now almost exclusively figurative. A riveting book, a riveting performance, a riveting argument. The tool that holds metal holds attention. The fixity is the same.
