Type 316 Stainless Steel Fender Washers are round thin flat washers with a larger outside diameter than standard flat washers of the same bolt size. They are used when a large washer diameter is needed to increase surface area and prevent fastener pull-through.
Type 316 Stainless Steel offer superior resistance to corrosion in Salt Water and Marine environments and resists corrosion when exposed to Chlorines, making 316 SS fasteners the superior choice for severe industrial applications.
