The Benefits of Stainless Steel Fasteners
Stainless steel fasteners are made of steel that has been mixed with at least a ten percent compound of chromium, and possibly other metals, so that the steel doesn't rust or corrode. This makes stainless steel fasteners great for outdoor conditions, where there is a lot of water or moisture. Especially if you are building something that supports a substantial amount of weight, such as humans, you will need to use stainless steel fasteners. Steel all by itself can rust until it breaks, and nobody wants that.
