The are used in places where ordinary steel screws would rust, such as in a deck which is exposed to rain and snow. The are also used where atmosphere would led to corrosion, as in a room with high humidity or gases which would interact with the base metal. They work very well, if that is what your question means.
How long do no screws last?
The “no” part lasts as long as the zinc coating remains intact. if the coating is damaged during installation, then rusting can start with the next rain. On the other hand, if the screws are carefully installed, and maybe even out of the weather, they may last almost indefinitely.
Why is zinc coating used?
So a zinc coating is most useful in environments where the metal is only occasionally in conditions where it can corrode. In those conditions, the zinc will last a long time before it allows the steel to rust. In continuously corrosive conditions, the zinc is used up quite quickly. Related Answer. Frank Robertson.
Does zinc plating rust?
The zinc plating will eventually break down and oxidize into rust. Galvanized coated screws will have a longer life span because the plating is thicker but being coated, they will also eventually rust. Stainless steel are the most lasting of all as they are all solid stainless steel and are not coated.

What Are Zinc-Plated Screws?
Like galvanized screws, zinc-plated screws feature a protective outer layer of zinc. Instead of dipping the screws in molten zinc, though, it involves a completely different method. Zinc-plating is a finishing process that relies on electricity to create a protective layer of zinc on the surface of a workpiece, or in this case, a screw. Basically, the screw is placed inside a container filled with water, saline and a zinc anode. Next, an electrical current is applied to the solution. The electrical current causes the zinc ions to bond with the screw, resulting in the formation of a protective zinc shell similar to that created with galvanization.
