Best Answer

The most common screws are steel, which is made from iron. Screws manufactured for special purposes are made from other metals, including aluminum, brass, bronze, copper, stainless steel, and titanium. Some screws may contain alloys of more than one metal, and steel screws may be plated with zinc, nickel, copper, etc.

Positive and negative refers to Direct Current. House wiring has alternating current. One of the terminals will be the hot, and the other neutral. The hot should go to the small metal tip inside the center of the socket, and the neutral to the metal sleeve that the bulb screws into. Typically the copper colored or darker colored screw is the hot, and the lighter colored (silver like) is the neutral, but check with a multimeter to make sure.
