The term "rivnut" is a shortened reference to a "rivet nut".
A rivet nut is designed to penetrate thin material and mushroom out on the back side to anchor itself in place. It is a method to provide a threaded base into material that would otherwise be too thin to support a threaded fastener.
These little inserts that you are offering, lovely and handy as they may be, are not rivnuts. They are basically 'wood-borne threaded inserts', or 'barbed wood nuts'. Even to borrow the popular term "wood insert nut" for this description, might be a better name for them.
You offer wonderful things, that one will not easily find at the local big-and-orange store. Keep up the good work.
