The act of securing or attaching things together, or a device used to hold things firmly in place.
From 'fasten' (to make firm) plus '-ing' suffix, making it both a gerund (the action) and a noun (the thing that fastens). From Old Norse 'fastan.'
Before modern fasteners, people used leather cords, wooden pegs, and ingenious knots—the way we fasten things tells the story of human engineering!
