They usually have a chemical coating on top, which protects them from the adverse effects that are caused by external extremities such as dust, water, and wind. However, rusting/corrosion remains to be the main culprit when it comes to screws losing their structural integrity over time. Therefore, builders and owners apply a zinc coating on the fasteners as its front line of defense against rust.
