Avoid rust streaking down the side of your project, staining, and stay corrosion free by opting for these passivated 316 stainless steel AN Washers instead of the more commonly available alloys in plain steel, galvanized, zinc coated, 18-8, 304, or A2 Stainless Steels that other retailers carry. We are one of the only sources for true 316SS AN960 Washers
What are AN 900 Series Washers?
AN 900 series washers have a smaller outer diameter, or OD as well as a specified thickness. An “AN” name comes from the fact that they meet US military specifications for use in the Air Force and Navy.
While most retailers won’t even carry this more corrosion resistant grade of stainless, it’s all we’ll sell because we wouldn’t use anything lesser ourselves when it comes to fasteners in a corrosive environment. We also like to set ourselves apart by allowing you to purchase these as you need them, and not be held to buying an entire box when only a few will do.
