Nuts and bolts are exactly what I am talking about. Brass, like SS,
have many different alloys in which some are better than others. I
should also mention that not all brass is usable for screws and nuts.
With brass too much zync and/or too little zync make most brass not
usable for screws. Too m uch zy nc and brass becomes brittle. Too
little zync and it becomes to soft. Aluminum can be added in small
amounts to make brass more resistant to oxidation. Also brass is
heavier than SS.

SS is not totally resistant to rust. There are several alloys of SS
that are less reactive with salt air environment. Yet eventually they
to will start to rust. Brass will oxidize with the salt air
environment. The oxide from brass is far easier to clean and less
evasive than that of oxidation from ferrous material. Ferrous oxide,
rust, will consume the entire ferrous metal. With brass, oxidation
retards as the surface area is coated. With brass the oxidation acts
like a protective coating and when there is no more exposed brass,
oxidation slows dramatically. Iron based metals do not exhibit this
quality.
