Some Stainless Steel Alloys May Be Magneticįrom time to time we get a frantic call from a customer worried that the fasteners they received aren't stainless because they jammed a refrigerator magnet in the box and the nails or screws stuck to it. To prevent this from happening, AISI type 316 stainless fasteners are recommended for any application exposed to saltwater (including immersion). This may cause color to bleed through finishes and lead to streaking in the wood surrounding a nail or screw head. However, in saltwater or other high chloride atmospheres, these alloys may pit and discolor. Generally, AISI types 302, 304 and 305 stainless will provide excellent corrosion protection in most situations. The properties of the alloys used to manufacture our fasteners are shown in the "Chemical & Physical Properties Chart". Solid stainless steel fasteners are available in several alloy types.
