Made from brass, these screws are corrosion resistant in wet environments, nonmagnetic, and electrically conductive.

Nylon screws are chemical and oil resistant, nonconductive, and lightweight. Exposure to moisture may cause them to expand.

One-third the weight of steel, aluminum screws resist corrosion in wet environments.
