Common Fastener Materials

Stainless Steel	Zinc-plated Steel	Hot-dipped Galvanized Steel	Chrome and Nickel Plated Steel	Brass and Bronze	Alloy Steel
Stainless steel offers good corrosion resistance, making it suitable for outdoor use and marine applications, but is more expensive than zinc plated.	Zinc-plated steel is a low carbon steel for general use. Relatively inexpensive, with the zinc plating providing moderate corrosion resistance suitable for indoors or otherwise dry conditions. Color is either a blue-ish tint or yellow depending on the exact process.	Hot-dipped galvanized steel has a thicker zinc coating for better corrosion resistance, making it suitable for outdoor use. Because of the thick plating, only galvanized nuts and washers will fit galvanized bolts. The coating typically has a rough, dull grey finish.	Chrome and nickel plated steel are smooth and polished for appearance. The plating offers moderate corrosion resistance.	Brass and bronze are copper alloys with good corrosion resistance. More expensive than steel, these materials are typically used For decorative applications. Colors can vary significantly.	Alloy steel is highly hardened and usually black oxide and/or oil coated, offering little corrosion resistance.
