316 Stainless Steel Fender Washers

The increased outer diameter of a fender washer will more evenly spread the load on the surface being bolted or otherwise fastened.  Our fender washers are a passivated 316 Stainless Steel Alloy, unlike the 18-8 or 304SS alloys that are more commonly found, and will hold up better in a corrosive marine environment. They are stamped on one side with "316" as seen in the photos, and the opposite side is blank and can be polished to a mirror finish if you desire.
