Bronze screws are 30% stronger than brass screws and provide more corrosion resistance to salt water, gases, and sewage. They are nonmagnetic and electrically conductive.

Bronze bolts are resistant to salt water, electrically conductive, and nonmagnetic. Carriage bolts have a smooth, rounded head for a finished look. The square neck keeps these bolts from turning when tightening a nut.
Bronze threaded rods are stronger and more resistant to salt water than brass rods.
Also known as single-start and self-locking lead screws and nuts, these have a single thread that runs the length of the screw. The nut travels only when the screw turns, so your system won't unexpectedly move when the lead screw is at rest.
Multiple thread channels (also known as thread starts) create faster linear travel than lead screws with a single thread start.
