Cap nuts, also known as acorn nuts, have a domed top that covers the exposed bolt threads. They provide a finished look and protect the threads from damage.
Flange nuts have a built-in washer-like flange that distributes the load and prevents damage to the mating surface. They are used in automotive and industrial applications.
