About Thumb Screw and Binding Post Materials

Stainless Steel—May be mildly magnetic.

Steel and Iron—These general purpose metals often come with a plating or finish. Zinc plating adds protection in dry, indoor conditions. Black-oxide adds a dark color, but no protection.

Brass—An excellent conductor of electricity, brass is often selected for its decorative properties. It is nonmagnetic.

Aluminum—At one-third the weight of steel, aluminum is strong and nonmagnetic.

Plastic—It's the ultimate lightweight material and is also nonconductive.
