Even Amazon has them. In black if you prefer. The fasteners are the finishing touches. In my book they are very important.

Those plugs are my preferred method because they are aluminum so you don't have to worry about galvanic corrosion. Brass & Steel plugs cause corrosion and pitting around the threads. They look better too.
